Hi guys, New to the forum, just bought my 1972 K-5 Blazer, CST package, 350 engine, 350 auto. I'm not at all new to GM 4x4's, I know the 73-87's in and out, and I own a 99' too. But this is my first 69-72 model. I know one of the first mods I would like to get is a rear disk brake conversion kit. Any suggestions?
