Progress! Being forced to stop work has some silver linings... junkyards are still open
Went to the yard looking for a flywheel and came across a medium case BMW diff with LSD.
3.91 ratio which I think should work. Out of a 89' 735IL. Looks to have the flanges that will work with the volvo IRS halfshafts. My next question is to see if the 960 driveshaft with the CV joint at the end is compatible with the flange at the front of the diff.
In the meantime a local volvo guy Matt (Uglyduck) was kind enough to turn town my pilot bushing on his lathe, so now it will fit the RN crank bore (at about 0.825" OD)
Then one of these showed up at a local yard
Finally!
And clutch is installed. Got a mounting face to pressure plate fingers depth of 3.3" (83mm) so I'm considering this slave cylinder solution
