Bel air

[Oklahoma]

A little off the beaten path here, but I'm looking at a 64 Bel air station wagon, but I cant seem to find any parts on the internet, can anyone of you tell me where I can find parts for these? will Impala parts work for this also? I told him that I was going to do some research before I purchase. it needs to have all 4 doors replaced, one finder, the grille, but the rest is in pretty good shape, pretty sure the gas tank will also need replaced if it can not be cleaned, and I think it is worth he is asking, besides when it is done it should be pretty cool. Thanks.
