Looking for something to upgrade my current 10 bolts. Would love to get ahold of a late model 3/4 ton/1 ton (eight lug) truck and get the diffs and trans/t-case out of. Not happy with the 700r4 and the 10 bolts. They will be going into an 88 Gmc Jimmy running 37 inch MTR's and 7 inches of lift. Lift and tires are on but have only put 40 miles on it since I pulled it out of the garage in Sept. Thanks for any help you can provide. Would love to get a dana 60 front and rear/14 bolt rear.
