Does anyone know what the part numbers were for the shifter and installation kit for the Avanti Hurst shifter? I know that the handle is NLA but after working on JDP's Avanti today I was finding myself wishing that I had an install sheet so that I could make sure all the rods, levers, etc were the right ones, and also this might prove useful to someone that already has one of these setups but needs a replacement part.

BTW the only way I could get it to shift well was to adjust it with the shifter locked in neutral and then lengthen each rod about 2 turns (moving the neutral gate forward) after it was all done - I might even have gone farther if I had more time to play with it.

The installation kit is #3157 - same as most T-10's, using the rear mounting holes.
The shifter was #6899.
Those were sold together as Competition/Plus #6898.
The shift handle zig-zags to the rear and to the right, to come up in the original hole. The shifter assembly bolts to the usual Hurst adaptor on the tail shaft. It didn't use the stock Avanti adaptor, which locates the stock shifter above the tail shaft.
As far as I know, the only installation sheet is for both front and rear mount kits. It lists individual parts for both.
What shifter assembly are you using? Which adaptor?

I don't know Mike, it's a car that had a Hurst shifter already installed. thanks for the numbers, I'll see if I can get an installation sheet for that. yes, I just wanted the breakdown of individual parts.

The installation instruction sheet is for both 3157 & 4734. I remember you bought a couple of 4734 kits; so I thought you had it.
The unique parts for 3157 are:
1-2 rod 213 2144
3-4 rod 213 2145
rev arm 105 1670
rev rod 213 2146
Forward-speed arms are the same as 4734:
arm 1-2 105 2140
arm 3-4 105 2141
You also need to check that each arm has the correct side facing out, that each rod hooks into the arm from the correct side, and that the adjusters are on the correct side of the shifter arms.

yup, I have done a couple Hurst installs on non-Avanti Studes, but the Avanti stuff is no longer listed on the Hurst web site, so I didn't know that the install sheet was the same :)

edit: I thought I'd had a .pdf of that sheet saved but I sure can't find it on the mess that is my hard drive, and it doesn't seem to be available on Hurst's web site. Anyone have a copy?

Also, the number for the shifter above doesn't work on Hurst's web site - has that also been discontinued, or simply superceded? I'm guessing a 391-7307 might work, but only because that is the only shifter listed for the listed applications for the 3157 install kit. (now I'm just being complete and trying to put this info into my spreadsheet for future reference.)

The shifter, 391 6899, was made specifically for Avanti's. It was announced in Nov of 1969, as a new product. It was still shown as one of eight shifters that will work on a T-10, on my 1988 instruction sheet. I know Hurst sold at least three of them! They haven't been available new, for some time.
The shift handle is welded on. Pictures of the handle, removed from the shifter, and the annoucement introducing the shifter are at:

I don't think any of the currently available handles are shaped like that. If you just come straight up from the shifter assembly, you will probably be at the edge of the console; maybe in the seat!
Has anyone tried one of the Hurst race car shifters, that mount on top of the tail shaft housing, and use straight rods? It may come out in the right place. It may be possible to use the stock Avanti adaptor.

I guess I just assumed that the shifter itself if not the handle would still be available, if it's not, does that mean that eventually even Dave T. will stop selling Avanti shifters?

I understand Dave uses a Hurst shifter assembly, (probably one designed for a bolt-on stick); with a stock Avanti stick welded on.
If the shifter bolts to the side of the tail shaft housing, with the Hurst adaptor, something has been added to the stick to make it zig-zag through the console in the right place. Because of the extra length, from the pivot to the boot, I doubt the stock hole in the console will accommodate the stick's range of movement.
If the shifter bolts to the stock Avanti adaptor, above the tail shaft housing, I wouldn't expect the 3157 Hurst rods and arms to work. Angles for the reverse rod would be extreme.
Hurst shifter #'s, at least on my '88 instructions, have a "391" prefix. Each includes a specific stick, which is also sold separately with a "238" prefix, unless it's welded. It's like the way the Competition Plus kit includes the shifter and installation kit, which are also sold separately. This continues down to individual rods and arms, which are available separately.
The stick is mostly what makes the shifter unique to a particular car. I even thought all the shifter assemblies might be the same, just with different handles. BUT, there's an indication that's not the case. Both shifter 391 7307 & 391 7308 used stick 238 7236. I wonder what the difference was.

Thibeault sold and installed a HCP shifter on my '64 Avanti.

Only thing I had him do was shorten some of the shift rods as I could not get into a few gears......all is fine now....eleven years later.
