I went ahead and ran a single 3 inch pipe to the back axle then 3.5 out the back to compensate for the bends. Sat. night with a couple of buddies I hit the trail. Broke a axle in the rear. Damn I say. Today at work I was trying to serve a warrant on a fellow and went to his neighbors house to ask about him. Lo and behold what did I see in the fence row covered in weeds? A 79 3/4 ton looking at me! Wanna sale that truck? You actually want to buy that thing? Yep.It dont have a title so $200.00 sound fair? I'll be right back. I came back with the money and a wrecker to get the truck. Old dude I was looking for was coiming out of his house and got him too! 200 bucks got me a 14 bolt SFF w/posi a dana 44, SM465, NP205, sit down......a 454 and I just dorve it around my back yard!!!!!!!!! (after a little work) I'll have the axles in the CUCV this weekend. The 205 goes in as soon as it gets rebuilt. Im actually gonna put the springs packs from the 3/4 in the blazer also. Everything measured out so should I expect any problems?
