pulled the trans and bell housing and found the arm pivot point is off about 3/4 inch which pulls it off the bearing. do I have the wrong bell housing or wrong arm?
What do you mean by off 3/4". IRRC the release fork has a spring clip that keeps it snug to the pivot ball in the bell. If it is broken, bent, or not holding it allows the release fork to flop around and fall off of the TO bearing. If you can wiggle the release fork in the bell and it's sloppy enough to contact any edges of the window in the bell the fork is not seated on the pivot ball. I'm assuming everything was fine before the clutch was replaced and all the new parts were the same.
