a body rear end ? 8 3/4 vs dana 60

Gotta add my 2 cents. Biggest problem with the Dana 60 is neglect. So good that you will forget its even there and that leads to neglect. I put one together using a truck housing, new sure grip,Cooks axles and green bearings. 5.38 gears for a couple of years than 4.88 Richmond street gears. Installed it in my big block dart over 30 years ago. Ran a 4 speed with 30 lb flywheel, clutchflight with same flywheel,metal disc,no marcel,solid hub and autos with 8" converters. No trans brakes. Always 12 to14" slicks. Never any problem. Not one. The same 88s do have a bit of extra backlash now however. For trouble free fun you can't beat a Dana.
