    1963 Avanti rear package shelf is sagging from water and age

    After a quick search online it appears no one offers a replacement of this part. I am referring
    to the pressed board with the trunk access door. Mine is drooping something awful and needs
    to be replaced. I'd thought about wetting it and trying to form it back, but I fear it will break
    up and not be usable for a pattern.

    Anyone replace one of these? What material did you use? I was looking at some marine use
    high density polyethylene, but I'm not sure if it will allow stapling and gluing of the new vinyl.

    The package shelf is made of wood. You could simply buy some plywood or particle board the same thickness and use the original as a pattern to cut and trim the wood to match. Then use some foam padding and vinyl to cover it with.

    Another alternative is to call Jon Myer and see if he has any good used ones from parts cars to replace yours with. Dan Booth at Nostalgic Motors may have a NOS one as well..he has a ton of NOS parts...maybe a package shelf might be among them.

    I used two pieces of 3/16" lauan plywood glued together to build the one in my 74. I left out the opening as I can access the lock through the 6X9 speaker hole. It wouldn't be hard to recreate the opening if you need one.

    I used the 74 reinforcing bar and attached the panel to the body with a piece of galvanized angle to add rigidity. All of the bolts were sandwiched between the panels to hide them when I glued the sheets together. I'm not a fan of foam under the vinyl here so I filled and sanded the plywood and then glued the vinyl to it.

    I used marine grade stretchable vinyl from Sailrite and glued it down with spray adhesive. It came out pretty well, I think.

    Good to see you posting again. BTW not much sticks to polyethylene, ABS might work but it's a bit flexi-flyer in my mind. It's working great for my door panels however. You can glue ABS.

    Not to side track, but glad to hear ABS holds glue. I plan n replacing both door panels and rear panels on the 63GT, using ABS as backing. (Have already bought the ABS.)

    It appears to be some kind of pressed board, like the kind used for peg boards with the smooth
    side and the cross pattern side that looks like little waffles. At least this is what they used in
    the first year. I kinda wanted to get away from something that absorbs water since this is an
    Avanti, its going to leak something, somewhere.

    I had considered aluminum sheet, but then I thought they might have gone with wood so that
    it would crumble in a rear end hit and not decapitate the rear passengers.

    I think I will make brackets to extend the reinforcement out to the sides to help support it from
    sagging in the future, looking at it, I'm not sure why they didn't do this.

    Thanks Bob, I'm around .. I just have WAY too many projects. I NEED to make a post about a
    project I completed on the 1969 Avanti with the power windows. I designed a bracket to allow
    the use of a $15 dollar GM motor in place of the $300 dollar (used working) long obsolete Ford
    motor. Once I found out this repair cost ... well .. you know me .. out with the old ...

    PLEASE make that post with the details on the bracket and the GM power window motor. If you don't have time to give us the details on the bracket, please tell us what G.M. motor you used.........year model etc., I can figure it out from there.
    Many thanks

    John,

    I will eventually post to find out interest and then 'RAD Ideas' will offer the bracket. I am
    already out quite a lot of money on my brake bracket effort that I need to recoup. Guess
    I should have pre-sold. I feel this is a very saleable product based on cost savings alone.

    Am I the only one who hadn't a clue what ABS is. I had to google it to find out what it is, but I still don't know anything more then it seems to be a plastic that can be melted to a liquid, re-solidified and melted again. ABS has always referred to a modern car's braking system. Anyone here willing to share some of the real world qualities that would make it better then then regular hardboard?

    Hardboard has lasted in Avantis for over fifty years...no reason it can't do so for the next several owners. Plastic will work and work fine, but wood is easier to cut, drill and shape, cheaper to buy so why not keep using it?

    Google ABS polymer and read the Wikipedia explanation. It's better than hardboard as it's tougher, glues quite well, more flexible and water won't hurt it. It the black plastic drain (DVW) pipe used in regions subject to earthquakes as it not subject to brittle failure as is PVC.

    Hardboard is usually more rigid and much cheaper so it is the choice for inexpensive uses like the Avanti deck panel. I like Lauan plywood better but no reason hardboard won't work here.

    ABS would be far from my choice due to the thickness needed and the much higher price it would command. But for door cards (panels) ABS is hard to beat.

    I'm planning to cut one out of plywood for mine this weekend. I'm thinking of coating it with epoxy resin, but the main thing is to stop that rear window leak.

    Agree with stopping the leak but coating the plywood should help. IIRC, they made a lot of boats out of plywood. Seemed to float until folks quit taking care of them.

    I was going to offer the tray out of the parts car I've got, but its already sagging too. Not horrible, but somewhat. It still has the support brace and brackets attached.

    Agreed, I feel the same way, the problem is, no one sells that thickness. All I can find is thin material, anyone have a source
    for 5/16 hardboard? This is of the oldest Avantis out there also, a 1963 round headlight. I need headlight bezels too.

    RAD Ideas is what I call my quasi-company. I offer my modern disc brake adapter brackets, I had planned to offer the power
    window adapter brackets. I have made an extremely stronger shifter stick for 2004-2006 GTO B&M Tremec T-56 (they break
    between the ball and the pin) and I just did a batch of sliders for seat tracks on a 1994-1996 Impala SS.

    Thanks for the offer, its Fawn or Elk .. faded and cracked vinyl. I am having the seats redone and the tray along with it.

    I had considered using heat to bend the board back, I tried to wet it, but found it won't take on water, I think they put a ton
    of glue on it and is soaked in. This could have easily been avoided had Studebaker ran the support brace from bracket across
    to the other bracket. I may just let the guy recover it as is, and raise the rear up for a nice gradual rake to the rear glass.

    Tom..........to be clear, you are not going to make the power window adapters, is that correct?

    I am replacing the rear shelf on my Avanti this week. I went to the local Home Depot and got sheet of 1/4 MDF board took the vinyl off the old one, and clamped the original over the MDF and just used a jig saw to trace/cut around the original. I drilled out the rivets from the brackets, drilled the holes and took off the brace, drilled the holes for the nutserts.
    It fits great in the car. I will be putting on new vinyl and re-assembling it this week.
    1 Family owned 63 Studebaker Avanti 63r-1705 White with Orange interior , R2 4 speed.
    Just purchased 63r-3623 R2 was a auto now dressed to a R3 with a4speed.

    I guess I need to check the forum more often. I was knee deep trying to get my 1963 Avanti ready for a large local show - lost track of time.

    I will be offering the bracket at some point, so far I have a rather large chunk of money into the RAD Ideas caliper brackets - would be nice to break even on that prior to putting out more capital. If you click the link in my signature things might make more sense about RAD Ideas, etc.

    I ended up doing very similar. I found the correct masonite hardboard in 1/4 inch and used the old one as a template. I used a sealant shellac on both sides and edges and threaded inserts along with pop rivots. Came out quite nice with the interior shop finishing the rear panel in the vinyl I bought. The two tone interior came out very nice, though the back seat wasnt finished in time for the show. It followed the next week and made its appearance at another show this past weekend along side my dad's 1969 Avanti II which my wife drove there.

    Thanks all that responded.
