    Guy is selling a 2 door belair HARDTOP 55 chevy body. There is no frame with the body. If one bought a frame, should it be a hardtop frame? Or will a frame from any 2 dr, 4 dr work? I do know that there are one piece and 2 piece frames. Thanks in advance

    The 4 door has is missing 1 body mount which is no big deal and the convertable is differant. A 55 and 56 is close but a restorer can tell the differance . A 57 is by itself .
  3. The only difference between 55 and 56 is the rear spring perch the only thing different from 56 to57 is the front frame horns, for the way the bumper mounts....There are 2 differnt frames either will work, one is a lil more desired then the other for customizers . there is a one piece frame and a 2 piece frame the one piece make for a cleaner custom (if your going for the show car thing )

    So you could use any 55 or 56 frame they are all the same wheel base and a 57 could work but you would have to change the front frame horns but If your doing a gasser and cutting them off , it would work.

    As for convert,Ht, 4dr or post cars most of the difference is on the bracing on the floor pans not on the frames. with a few minor exceptions

    What he said, with one exception. A four door hardtop (also referred to as a sport sedan) has the No. 3 body mount positioned back just a tad from the other body styles to accomodate the floor crossmember specific to that car in order to stiffen the B-pillar that attaches to nothing at the top, but still needs to swing/support the rear door.

  5. If you are not absolutely set on using a 55-57 frame, consider that they have a 115 inch wheel base. most gm big cars from about 78 to 86 have 115 to 117 inch wheelbase with disc brakes, power steering, decent rear ends and suspension parts are cheat. Try pricing an idler arm for those triple 5's and then consider that every piece of it is proportionally priced.
