    This was a subject in the past that there is some bad information about. If someone has more or better information please post it. Someone in the past has said that 61 bushings will not work correct in 62 and 63 but I am finding that you can. I have a set of 61 NOS bushings, a used 61 crossbar and a 61 car to compare things to. I just pulled the original bushings from my 62 crossbar, the 61 bushings will fit just fine in their place. Also the 61 and 62-3 body mount locations are made exactly the same with the same size spacing and holes. Someone told me that you have to make a shim to space these bushings but I think it was because they did not understand how they work. When these bushings are new, the center looks taller if you are comparing to the old bushings. It appears that the center will “crush” to the proper height as you torque the bolts down. The center will bottom out on the cap that is on the bolt and preload the bushings.
    The bolts are also different between 61 and 62-3 bolts. The collar on the 61 bolts are much longer than the 62 bolts but the overall length of the bolts are the same. From what I am seeing this will make no difference at all because the collar stops inside the bushing and does not bottom out so either bolt can be used. Just be aware that the 61 bolts are fine thread and the 63 bolts are course thread. No big deal on the back because it uses a nut but on the front the nut in welded to the body. You will have to use the proper bolt there but the back bolts can be used either way.
    Overall I am not sure why they changed the style of the bushing and bolts but wanted to at least post this information for anyone searching for bushings. This way you can use 61-63 all for each other. Now I just need to decide if I will use the 61 NOS bushings for my restoration or use the originals. I have to use the original front one because I don’t have that one NOS. All of them look pretty good so I think I will just reuse the originals.

    Well, I stand corrected. I based that on another member using 61 mounts and not being able to get them fully home in the Upper unibody Frame member. Had some pics and everything.

    If that’s the case I sold some NOS 61s I could have used, although mine are in decent shape it would have been nice to have some unused ones in there that the car hadn’t been sitting in for 60 years!

    I understand a jagged upper rubber washer would fit the jagged top of the 61’s but never have seen those for sale.

    Good, at least a little broader option. Look forward to your final fit.

    I couldn’t remember where all I heard it but I know one time was at Homecoming last summer. This is something I wanted to look into for a long time but was never in a position to be able to. With my car home and apart and the 61 still here (I am about to scrap the 61) then I figured I had better do it now.

    With as many revisions as these cars went through I would not be surprised if there is another setup that I do not know about.
