Ted  Schumacher mentioned that the aluminum bell housing uses a different  
release bearing sleeve. Does anyone know how to tell the  difference??

I don't have any MkIV or 1500 parts books handy, but I do have them for the  
earlier cars. From what I can tell, both the throwout bearing sleeve and 
"clutch  disengaging lever sleeve" carry different part numbers between early 
Spitfire  (coil spring clutch) and later Mk2 and beyond (diaphragm clutch). 
 
Also, from what I can tell, the diaphragm clutch uses the 7/8" bore slave  
cylinder. How to tell the levers and sleeves apart, I don't know (unless there  
are part numbers on them); sorry!
 
As for the alloy bellhousing, I don't think that matters in regard to  clutch 
action...except possibly that there are a couple variants of the alloy  
bellhousing. There's one with a rather thin flange as used on Herald 948 and  
earlier 1200 models, and there's one with a thicker flange as used on earlier  
Spitfires (but which should be usable on any three-rail gearbox, AFAIK). I don't  
know offhand if there's a difference in overall depth between those two  
bellhousings...but I can measure if anyone really cares! ;-)
