OK, after much deliberation ( a.k.a. pleading to my dad) I have decided to put a 14 bolt FF and a 3/4 ton dana 44 under my (our) 71 K5. I know its pretty much a bolt up on the later models of blazer but is it the same on mine? I have heard that on the back all you have to do is reposition/weld shock mounts. Is this true or is there far more involved, also how about the front end, is it a bolt up besides driveshafts or is there also a lot involved? Thanx in advance Theres No Replacement for Cubic Inches!
