clutch hydraulics

[FMags2@domain.elided]

I've just started rebuilding all of the hydraulics, starting with the clutch 
master and slave cylinders and am already running into problems from the work 
of the POs.  

Question #1:  My clutch slave cylinder had two 1/2 inch spacers between the 
cylinder and the bell housing.  I assume that these are not stock, and was an 
attempt by the PO to make up for a slipping clutch?

Q2:  If the clutch is worn to the point where it was slipping and assuming 
that the remedy above fixed it for now, is there any danger of damaging the 
flywheel face?  I suppose it all depends on how much the clutch is worn.

Q3:  My clutch master cylinder pushrod had evidently been broken in two 
places and welded back together quite badly and is not very straight.  It 
measures 4 3/16 inches from the tip to the center of the hole for the pin 
that holds it to the pedal.  Is this the correct length?

Q4:  Does anyone have a spare clutch master cylinder pushrod that they would 
like to part with?  Even if mine is the correct length, I'd like one that is 
at least straight.

Thanks in advance,
