Hi Joe,
And thanks for the help Jane Ann!!
Yes that's almost exactly what mine looks like in the tunnel, it's pretty close to that nut/bolt on the side just like yours. When I bolted the tailshaft in place I was looking for a reason as to why it was so far shifted and couldn't find one up front. The bolt holes lined up dead nuts in the crossmember. But maybe it's at a slight angle and you can't see it up front, it gets more pronounced the further back you go.
The differential must me offset as well.
Looks like a brand new shiny driveshaft, did that help??
I haven't driven mine yet so I can't report on any change, my radiator was seeping a little so I removed it and decided that since I had that out I'd see about swapping camshafts, then that lead to "geez, why not get some better heads?" If I don't stop myself, I'll never be driving this thing!
Bill
