The 8 1/4 thread
Geardaddy- thank you, yes I think I am going to plug Dana 35 internal into an 8.25. I will advise as I go. I bought one with a locker, 3.73s, brakes and all the plumbing, so really if do not plug the internals in, I feel I am in a good position financially with the brakes and plumbing. I trust it will fit as stated above, however my concern would be strength and longevity behind the Gen III.
