I called T/A Perf. And spoke with Tim on Buying the Correct TA RearEnd Girdle.Tim told me to measure center to center of the bolt@12:00 to 6:00 to get the distance. 9-3/8"spacing is a Chevy 10 Bolt. 9-3/16" spacing is a BOP 10 Bolt. I have to measure the spacing to determine which Girdle to Buy. Whether its the 1807,1807A...or the 1808 Girdle.I Thank Tim, for the info...Jay B .Britt,Jr.
I answered your other thread. 1807 or 1807A is the cover for the 8.5. You are sure it is an 8.5, right?
Yeah interesting design with pan hard bar that could be attached to frame a little stouter, but the adjustable pinion angler is really cool, it's the one part that all I have ever done is check the level, almost afraid to pull cover and inspect an new oil it
