I need some help. I have a '74 Dodge 3/4 ton Dana 44 that I want to convert to disc brakes. After reading this article on the offroad exchange: ORE disc brake swap I found out that GM front ends do not have the caliper mount cast into the knuckle like a Dodge Dana 44 (no need to change knuckles, and apparently 15" wheels fit GM 3/4 ton calipers easier). My question is, what front end do I need? The article claims that 1978.5 and newer 10-bolt parts is what is needed. Is this true? How do these differ from the GM Dana 44 parts?
