i know this is one of those things that has been beat to death but i remembered something from a while ago and needed some help. MEPR had said one way to get 5 lug and better brakes would be to replace wheel assemblies off of a k5 blazer 2wd or any early 2wd 1/2 ton. does anyone know anything about this and if so how easy is it? my brother in law has just stumbled across such a thing for a parts truck and i was going to rob the front end off of it if it will work. any info would be nice.
if it matters at all my truck is a 77. thanks
