I have a 76 gmc pickup. It was half ton it's now 3/4 ton. It has a 500hp 496. 6" springs corp 14 bolt, dana 44, th 400, np 205. Its just waisting away in my dads back yard. two weeks ago I blew the rearend in my 99 burb. I work at currie enterprises so i dint see parts being a problem. ANy ways to make a long story short. I was ticked that i had this truck with all these awesome components that i couldnt use because It doesnt have any smog equip. Its green stickered. So now I decided that I need a backup vehicle. I've been planning on building up my rig into a sand buggy like john currie is doing with his tj. Any ways now the question is will diffs from a 76 gmc pickup bolt up into a 70-72 blazer, or should I get a 73 blazer? Any direction would be greatly appreciated. i personally like the looks of the 70-72 blazers but I got a lot of crap that I know will move right over to the 73. A suggestion my buddy gave me was take his 73 pickup and move my stuff over or just move his vin over then register it in my name and scrap my old truck. But I plan on hacking whatever I do beavuse I want to hold at least 5 people. So I would butcher the cab on that truck. And then not be able to get it insured by any one. Any body seen zach steeles blazer. It was in petersens last year white with blue and white checkers, thats basically what im wanting to do. Any suggestions ?
