Tonight i got to installing the 4.10 carrier I recently got from a forum member. The oil in the rear looked like its been in there its whole life. I know for a fact its been in there since at very least the early 70’s. Install went pretty smooth minus 1 u joint strap being seized into the rear end. I coaxed it out with the trusty air hammer. Got it all together and took it for a nice test drive and went up and down the highway to see how it felt at speed. Its definitely tolerable now and my next plan is to install my full syncro 3 speed with a borg warner overdrive. Then it will really be a nice cruiser but for now just the 4.10’s are pretty good.
