Hi guys, this is my first post and i hope i don't start off with a stupid question but here it goes, and I did check knowledge base if i've overlooked the answer my appologies, anyway i've got a '86 chevy s-10 with a 350 sb . I was wondering if i was going to lower this truck is there a specific degree the driveshaft/rearend must maintain. The rearend looks like it has moved alittle already, the angle where the driveshaft goes into the diff looks alittle steep. I did by the truck about a year ago from my buddy, and I don't know any history of the truck. thanks.
