    Hey Guys,
    In pulling the interior on my recently acquired '73 GS, I found some heavy rust in the lowest points of the front footwells that seems to be too pitted to grind down so patches are probably in order. The affected areas are like 8" x 8" max so these will be patches rather than full floor sections. I have checked all the usual sheetmetal vendors and no one can tell me if the front floor patches interchange between the usually listed models (Chevelle/Laguna/Malibu/Monte Carlo, Cutlass) and the Century. I am prrrrreeety sure they should interchange but I wanted to see if anyone has been down this path already on the colonnade era Buicks to know for certain. Thanks!

    Some years ago I used patch panels from a Monte Carlo for my 74' gran sport. I think I got them from NPD. But a couple years ago I got ones specificaly made for my 75' Regal. They were nice replacements. Summit sells them and they should be the same for your car.

    I used the 73-77 Chevelle front floor panels in my 73 Buick. No difference.
