I was very lucky as well, we needed all new sheet metal and we found a complete front clip of a 1970 in a junkyard back in the late 90’s. AllAll aftermarket metal panels both inner and outer fit like crap including upper and lower dashes and end air vent pieces.
I would fix the originals any day before buying sh!t.
I was lucky when my car was done in 1985. All panels were still available at your local Chevy Parts Dept. Whoever thinks aftermarket is great, just has no clue.
original and rust free. Sure saved us from using reproduction body panels on the front end.
