I'm doing a Dana 80 swap from a '00 Chevy HD3500.
I'm NOT a master mechanic and am trying to do it and it's going OK so far (other things are getting in the way)
Also trying to get the front solid axle under my '64 2-ton stake truck.
BUT, the tag is showing a 5.13 gear!! I wanted to install a Allison 545 but that doesn't have an overdrive.

Anywho, it's in my 'dustlessblasting' business build (to use as a rolling testament of what the blaster can do.

PM me your number and I'll try and answer questions if i can.
