Ok, so a local scrap yard has a K5 roll bar on craigslist for $50. I have an '89 Blazer an I want to know what I need to look for when I go look at this. The only thing the scrap yard could tell me is that it is out of a late 80s K5, he thought. The yard is about 2 hours round trip from me so I want to be prepared when I get there. I've never put a RB in a rig before, so any one out there have advice?
