I know about the driveshaft and trans crossmember issues, my main concern is the flywheel and clutch. Mazdatrix sells a clutch disc that is N/A sized but has the TII splines, presumably so you can stuff a TII tranny in with your stock flywheel.

If you do that, how will you get the starter to work? Isn't the TII flywheel larger in diameter? Or is that why TII's have a different starter... same mounting location but drive pinion offset to mate with the larger diameter flywheel?

 

The clutch diameters are diferent,
The ring gears/teeth on the flywheel have stayed the same since the 70s'.

 

Ok, so I would just need the TII trans/bellhousing and the TII starter? (Besides the mount/driveshaft fabbing)
