[67C10Step]

I fought a similar issue on my son's Toyota Tacoma for a while. Toyota flunked drive line 101 because his truck is completely stock and the trans tail shaft was 2 degrees down but the input on the differential was 4.5 degrees up. Got some 2.5 degree shims and it took out 99% of the vibration. Still has just a bit but nothing compared to before.

By the way, I like everything about this truck and build. Love the back glass treatment and color choice.
