so did the conversion to an 8 3/4 actually work??? I was reading a little further back and saw you saying that it didn't work out. I'm just interested. Are the very first pics you posted from the 8 3/4 swap or the 8 1/4??
The caliper bracket fit good on the 8 3/4 after we drilled the fifth hole in it, the same with the dust shield. The Rotor is the big bolt pattern and my axles are SBP so when we noticed the off set problem we made the decision to put the disc brakes on the 8 1/4 rear end under my son-in-laws dart.
I still need to get BBP axles for my 8 3/4 and wasn't ready to do it yet so we figured we might as well put the disc's on his ride.
If someone can figure out the off set problem on the 8 3/4 it would be a fairly easy swap.
We spent total some where around $100 to $150 to make the swap on the 8 1/4 That included new rotors.
