<VV> removing input shaft seal

[John McMahon]

While I've got my differential and tranny off the engine (1965 Monza with 4 
speed), I'd like to replace the input shaft seal (and throwout bearing, of 
course, and pilot bearing too).  Does anyone have any tips on how to remove 
the thick retaining ring for the input shaft seal?  I'm sure I can get it 
out, but I'd like to do it without damaging the throwout sleeve!  I've 
thought of drilling holes in it so I could use snap ring pliers, but that's 
the best I've come up with so far.

Thanks,
