Tiny update:
And yes it's held in place with it's own hardware, jackstands were just used to help me keep it level while I jacked it up with a floor jack.
And some pics before it went in all put together. So nice and clean!
This one you can kinda see the cleaned up diff cover bolts, and the cleaned up diff to subframe mounting bolts. Details...
And last one shows the homemade poly diff ear bushings in place. Basically goes subframe, large washer, poly bushing 1, diff ear, poly bushing 2 (stock metal insert is reused in the middle), then the stock concave washer cleaned up with a coat of silver. Thanks again K-dog
