I just bought a 1961 impala bubbletop very original new mexico car. The color is (925)Corna Cream/white with (865)Fawn beige interior. Its a numbers matching 348 4 barrel car. Any idea if these cars had buildsheets like the later 60's chevys and if so where are they commonly found in the interiors???? I havent even picked the car up yet took look. Whos the vintage Impala guy to talk to??
