8.25 suregrip

If your current rear end is an 8.25 & you swap to the 9.25 only thing you may halfta do is shorten the drive shaft some to fit correctly. Or if the doner for the 9.25 is same wheel base & same drive train just bigger rear diff grab its drive shaft too & presto! cook both tires & once! If that's out of a Dakota it would be a real early Dakota. Most Dakota SG diffs ive seen have been the TRACK LOC cheap clutch style unit. That's a cone style SG Nice unit & re work able if ya know what yer doen.
