Problem: Bitch clip is a BITCH to remove (That is the clip that slides through the bushed end of the shift arm - connecting it to the top of the tranny)
Solution: spread, flatten or remove the tab the keeps the bitch clip from swinging up OR just use a bolt instead.)
Problem: Hex bolts on top of diff are hard to reach
Solution: cut holes in trunk over the bolts big enough for a socket on an extention to reach the bolts
Problem: hex bolts on top of diff are hard to align/thread into the diff
Solution: Replace bolts that screw from the top with studs mounted in the diff and a nut on top (easier to thread a nut on top once the stud is through the hole than to thread the bolt from above)
