  • Correct transmission mounts - what to use?

    I am posting this for a friend who has a 54 Starlight coupe. He is installing a 289 with a flightomatic. He is trying to purchase the correct transmission mounts. The vendors show mounts for 56-57 cars and then a different set for 58-64 cars. My parts books do not include those years. Studerbakeronline parts show the 56-57 to be part number #ins204 and 58-64 to be #ins208. We do not know what year the transmission is from. What is the best approach for him?

    Is the transmission a long tail shaft or a short tail shaft? That should be the difference in the transmission mounts.

    57 and older is short tail shaft and 58 and newer is long tail shaft.

    The best approach for him is to understand and know what he has for parts, what years and models. Then he can inform the parts people.

        Do you know anyone who has a Studebaker V-8 car with an automatic transmission installed in it? You could measure that. If one assumes that the transmission is correct for the year of the car you can extrapolate the answer.

        Failing that, your friend could order both types and return the one that is not correct. I generally advise against returns as it disrespects the vendor.

          My 289 in my 53 coupe was from a 63, I guess the trans might be the same.

            All that really matters is whether or not it has the correct to the 1963 Car Year, slide-in opening for a slip Yoke & ONE piece Driveshaft.

            However the Flight-O-Matic Converter Housing HOLES that the Rear Engine Mounts attach to, are all THE SAME. That means that among '56-'64 Flight-O-Matics, the Trans. year has NOTHING to do with the Type of rear engine mount at all.

            It is the Body and Frame that changed causing the different Mounts. it is unlikely that EITHER mount will drop into the Frame holes, the Flight-O-Matic Frame hole location is not likely to be the same as the Detroit Gear Auto Trans. rear engine mount holes, so they will need to be drilled.

            The Center Support Crossmember will need to be partially or completely cut out, to install a ONE Piece Driveshaft.

              The '53 - '57, short tail shaft, transmissions, were used with 2 piece drive shaft assemblies. '58 and newer were used with one piece assemblies. As long as you use the correct tail shaft and drive shaft combination, either should be Okay!

                18" sure sounds like a long tail to me.

                  The only difference between the INS 204 mount set and the INS 208 mount set is the location of the hole pattern where it bolts to the bellhousing side.
                  The 204 set, what I call the Lark set (plus ‘56 - ‘57 all), allows the bellhousing/transmission to set somewhat lower than does the 208 set, what I call the Avanti/Hawk set (‘58 all, ‘59 - ‘64 Hawk, Avanti)
                  A few years ago, I had a ‘63 Cruiser that the front u-joint yoke would hit the floorboard on certain occasions. I found that someone had installed the late Hawk mounts, which raised the transmission so that the rear especially was too close to the floorboards. I installed the Lark mounts and all was well.
                  I am guessing that, considering you have the early floorboard style, that the INS 204 would give you a little more desired clearance. Don’t forget the 1/2” spacer on the driver's side.

                    Thank you, really good information. He is installing the 1960 289 With flightomatic into a 54 starlight Coupe frame. At one time with this frame had a 289 with Slota Mattick with a one piece driveline. We pull that engine and transmission and put it in something else and there are no mounts anymore but the holes in the frame are there now. He has not got back with me yet on whether his tail is the same length as the flightomatic that was in it before. I have been passing on all the information that you guys are giving me to him.

                      All ‘58 to ‘64 FlightoMatics are the same length.

                        His is an 18" tail also, so long tail. He is ordering the 204 mounts. Thanks.
