51phatboy, you're gonna want spindles from an early ('67-'69) Camaro or your era ('68-'72) Nova. The early and late (front-steer/rear-steer) spindles won't exchange. There are conversion kits available, I believe, to swap the drums you have for discs. Try here:
www.classicperform.com They offer all kinds of stuff for this type of conversion. Best of luck.
