Check the Tech tips on Jim Carter's site. I believe the 4.11 only came 67-72 for the 3/4 drop out rear. If you find one, it is an absolute straight swap. If your truck sits high like mine, you don't eve have to jack it up! Pop the axels at the hubs, unbolt the pumpkin and u-joint, repeat in reverse. The rear end housing doesn't move during the swap. If you use the 14 bolt, you end up having to do the machine work.
Current fleet (subject to change w/o notice) \'49 GMC 3/4-Ton , 60 Austin Healey Frog-eye Sprite (some assembly required), 2011 Dodge Avenger, 2015 Jeep Cherokee. No, they don't all run. My other ride is a (B737)no, (B767)no, A320.... Update... was Embraer E190, now Boeing B787. Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
