I've read somewhere that when using GTA wheels, you need spacers in the rear? Is this true? I have an '86 with rear posi, and 16" wheels, and I just bolted up a set of GTA wheels. I haven't drove it yet, except out of my driveway, onto the curb, and their doesn't seem to be any problems. Just want to check, better safe than sorry.

nope you don't need any spacers. From what I was told the spacers were included to prevent the wheel from corroding and getting stuck to the drum. as for the disc brake setups i was told that gm didn't use them. Know as far as how accurate that is i don't know but that is what i was told.
