Little or no support in the resto/aftermarket for C body floor pans.
1. Fab your own & weld them in
2. Search for good used southern rust free metal.
3. Good luck
All my sheet metal repair on my C was a combo of 1 and 2.
FYI,all Formal C wagons had the same wheelbase and the floor pans are also the same between Chrysler,Dodge and Plymouth.
E bay?? No no no...It is a C body.Sure most mechanical schtuff there and the odd NOS switch or trim tidbit.
You Gotta go underground to expand your horizons LOL
Do some networking,eh??
Hope this helps
