Bought parts for my build from all over the US and Canada about 7 years of chasing Baldwin/Motion Performance parts from the 70’s
Car parts from all over..
I used Tempest search engine which searches all the states in the US for Craigslist
Any large body parts fenders or whatever I used Greyhound if the seller would do it..lots cheaper
Also try Yenko.net lots of very big car guys over there and they might be able to dig some up for you..
I found this on Tempest
Maybe it will help you..good luck in your search
