The rear axle is a Dana 60. I would much rather just replace the "pumpkin" but I am not able to locate one and then it would probably be a 4:11. I don't have any plans on using the truck other than driving around town for fun.
I also bought a GM C&C dual wheel axle for its narrow with but it looks like a monster rear end and probably will not use it.
Thanks for all the impute and insight.
