I came across it a while back, not long before I decided to get the H2B bracket. I would have to find it again.
I'm guessing the flywheels have the same bolt pattern, and the matter of just lining up the transmission and marking the holes to get the right orientation.
Then just drill them out.
If I find the thread I'll post it up.
I don't have a D-series tranny and flywheel off-hand, but bolting those up and lining everything up to do should take about 15-20 minutes. Add a little extra to make sure the intermediate shaft gets lined up as well.
