The best bet is a new belhousing , several people make good ones , I would contact Brewers , , they will have any parts you need .
Crossmember & driveshaft / yolk are all the same as the 727 auto .
I would recommend a McLeod 10.95 " B&B/Long clutch on a 130 tooth flywheel .
teh crank can be easily drilled for clearance as long as you use the Dakota roller pilot brg .
