Here is the rearend mounts.
The rearend is the 10 bolt out of my 68 Chevelle
when we replaced it with the correct 12 bolt.
I was able to use the stock mounting bracket for
the top of my model A wishbones but had to fab. up
a lower mount.
The shackle mounts will get additional bracing
and will be welded fully by stick and not mig in
hopes of additional strength. I still have to finish
makine the rear and front bone mounts.

I hope that the rearend will not bind with the
way it is configured. If it does I'll probably have to
move the A bones in toward the center more. The
fingers are crossed.
