I think I can pull it off.... Has anyone else tried this? Drill mod without removing the master cylinder. Yes I'm Lazy!

 

I don't know man, I think trying to knock that retainer pin that holds the line onto the m/c out and back in would be a royal PITA with the m/c still installed on the car. Another thing to consider is that when you take the line off the m/c you will be introducing alot of air into the m/c and it more than likely will need a good bench bleed. Personally, I would go ahead and just remove the m/c. It really isn't too bad of a job and will more than likely save you some time and headaches.

 

Seems like you got some good points. So I'll wait till I got sometime to pull it all off and drill it. Thanx
