The rust spots are the same as the 55 Chev . Floor pans are available from Cross Canada and are the same ones you would buy from CARS in Michigian as they use Cross Canada as one of their suppliers. I used the floor pans rockers and quarter panel patches and they are OK.
Who is the best reproduction parts company for trim/interior,mechanical,etc.?
I have never found any source for new reproduction trim/interior parts. Only eBay. Except body gaskets, rubber, etc. are same as Chevy and readily available reproduction.
Mechanical is all 55-57 Chevy, parts suppliers galore, here are ones I have used:
Oh, btw, I am no expert on rust, my Canadian Pontiac spent most of its life in California, and is pretty rust free, frame especially. So I can't help there.
