I picked up what was left of an 86 GMC cab chassis 159 inch wheelbase. A couple questions:
1) the build sheet says G80 limited slip-- Is that the dreaded "guv bomb" when jacked up it acts like a regular differential -while one wheel spins forward, the other one spins backward.

2) This has the narrow rear end- if in the future I want to install adapters and diesel wheels do I need the wider rear?
