I may need a slightly shorter than my G body 52.5" driveshaft, using a 3R to 1350 conversion U joint. Ironically the stronger and 1" shorter 8.5" driveshaft would be perfect for my 4L80E conversion. Finding one, good luck. I am looking at an aluminum driveshaft out of a 2014 to 2017 GM 1500 4wd. A quick reference mentioned a 534G, which looks like a 3R U joint. Another problem is the drivershafts on Amazon are total driveshaft length. Any input would be appreciated.
