you're better off to fix your old ones if possible,i had new goodmark repops installed on my 69 this past winter.drivers side bolted up nice but the passenger side was a nightmare,lots of extra cutting and hours involved to make it fit half decent .plus at $500can a piece you can do a lot of work on you're old ones for that kind of change.i bet by the time my bodyguy got done with my passenger fender i was close to 8-9 hundred.
