This reminded me...
I have a stock brake master cylinder in my Pantera.  I also have  
another beefier, USA Ford style master cylinder that a generous person  
on this list sent me years and years ago along with other front brake  
parts.  It does not appear to have a spacer with it however.

So, being that I can't source a rebuild kit for my stock master  
cylinder, I -could- use this other one, but I need to know the  
specifics of mounting, rod lengths, etc.
