1988 14 bolt options
I have a Factory 4.10 gear in my 88 R20 Suburban. Im gonna be driving it alot this winter and would like to try and get some better mileage out of it. Ive never messed with rear ends much. Other then swapping in a mini spool, and a power tracs. Ive seen some 14 bolt rears cheap on craigslist. What years swap with this truck? Also how can you tell if its the 9.5 or 10.5 ring gear without taking the cover off?
