Lookin to swap from drum to 4 wheel disc, but would love to keep my 14" wheels and hubcaps. anyone know how i can do this?

It depends on the disc you want to install. If you install 69-72 style front discs you won't have a problem up front, they ran inside 14-inch wheels in 69 and 70. As far as the rears, you just need to pick a rear disc kit that will fit. Anything 11-inch and under should fit.

wow didn't know it would be that easy. I have pretty deep backspacing (unsure how much exactly) but that should help the situation right?
