Jeremy,

	BTDT.  You do indeed have the '89-on Quattro centre diff(mine says
M021-DHU).  This is the standard unit supplied by Zexel.  We were told
that the Quattro diff has involute teeth on the spline, but that it wasn't
necessary to duplicate the involute feature.  He told us to use straight
sided teeth. 

	Forget using Quattro driveshafts.  They are almost a grand each.  
We had some custom cut for us.  They ARE worth the effort.  You won't 
believe how well it works in an SAE car.
