Are you going to be using the AHB 8.25” or getting the jeep rear end? I purchased a AHB rear from a member here and rebuilt it with SureGrip and 3.21 gears. The AHB 11” drum brakes stop real nice too.Fantastic information. Exactly what Ive been looking for. I just picked up a 8 1/4 from a 87 Dodge diplomat police car to swap out my 7 1/4 . Is the firm feel kit a direct bolt in? Thanks again.
