Re: [ihc] Master Cylinder question

What's the easiest m/c swap?  I've heard that there is a Corvette M/C 
that bolts directly in (even bolts to the Scout II booster), but then 
other people say it needs modification.

Checking that m/c in Delco's web site shows it to be a common item (111 
Chevy applications, not limited to Corvettes) but I'm still looking for 
a definitive answer.
