Thread: Mount a 1951 body on a 1973 riviera frame

    Mount a 1951 body on a 1973 riviera frame

    I have a 1951 46s and I was wondering if I could mount the body on a 1973 riviera frame. This would give me the 455 and newer running gear. I was wondering if anyone has done this switch or if there is any information on the two frame sizes and if they will work.

    1951 46 wheelbase = 121.5

    1975 Rivera wheelbase - 127


    But I have read about guys putting old bodies on 1970's chassis. You just need to select a better match

    anything is possiable

    you have to measure width and length and maybe relocate some body mount holes..


    just put a s10 chassi on a 53 chevy truck .... its not about if it will fit its about how much dedication do you have to make it work ...
