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!
the share frames and glass so they should ive not been down this path but idk why it wouldnt be atleast super close.
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.
so it begins. pulled up the carpet to find this. looks like water pooled on the inside from a leaking window seal.
Ended up cutting more that the photo above to get to clean metal and finesse out the spot welds connecting the toe board area to the underlying body Mount box/bulkhead.
They were from OPGI. Took a bit of tweaking to get everything fitted up but I’m happy with the result
from a Chevelle or made generic for all 73 -75 A-body? Any information provided can help those that need to do the same thing! thanks Fernando
The catalog had them listed under Monte Carlo but I think all the A body front floors/toe boards are all the same (as mentioned by others earlier in this thread) with all the 3D curvature, I don’t think a job like this is ever plug and play- there will be a lot of fit up and trial and error to sneak up on the right fit
Hope that it's not too late, but make sure that there aren't any leaks before you reinstall the carpet. On my car, two of the three vent inlets located in the cowl had no sealer.
