LOL, I found the problem. The reverse light cable got wedged between the tranny and the block at the top. Now it's in two pieces
I was underneath lifting it up, but got smart after a while and ran a rope from the rafters down to help support the tranny.
And yes, I did use an alignment tool.
I have another question though. Does anyone know the sizes of the two bolts that hold the driver's side axel brace (the part half way between the tranny and the hub). Hopefully I will find them in the light, but was having trouble just now and may need to replace them.
