The alluminum flywheel sounds great from a weight savings point of view but ... its one of those conversions that unfortunatlely lacks all the pertinent details to make the swap successfull.? Unfortnately I do not remmember what that particular detail was, I vaguely remember something about modifing the T/O Bearing carrier (?)? There are 2 different T/O bearing carriers: one is for the very early Spits with the 3 finger B&B pressure plate/ flat flywheel.? The other is for all the Spits with the diaphram laycock pressure plate/ recessed flywheel.? No I do not no which is for which just that one is longer than the other.?
 

As for the bellhousings ... cast iron versues the alluminum there is no dimentional difference, between the gearbox and rear of the engine.? Thus they are very interchangable with no secrets to make the swap other than what has been stated about the thin versuses the thicker alluminum casting.? From prior experience you DO NOT WANT the thin cast housing, it WILL CRACK radially around the flange and cause severe problems.? How can you tell if you have the thick alluminum bell housing?? Hold it side by side to a cast iron bellhousing -? it should look as if it came for the same mold, flange should be the same thickness as well as the rest of the unit.? The thinner alloy bellhousings have a smoother less ribbed finish? and obviously thinner all around compared to the iron bellhousing.


The alloy housing will bolt up to the GT6 gearbox for those going for a CR Gearbox set up.

Good luck all,
