I just bought a pair of moser axles for my 8 3/4 a body rear end. Is it normal for them to not have the big hole in them to get at the nuts that hold the bearing and backing plate on?
the stator supports on the pumps differ between the lock - up and non lock - up trannys, so you should switch the pumps. check to see if your front clutch hub has 2 or three sealing rings as well some years differ.
scotch brite the servo bores and try using teflon rings. Or get a unpgraded servo with dual sealing rings. Performance automotive and tranny center makes these. No leaks
