Re: Manual to Power brakes question

The hole in the firewall doesn't have to be welded. Cut out a plate the shape of the mounting area of the clutch MC, drill two holes in it put a bead of silicone on the back and bolt it where the master cylinder bolted. I did something similar to this as my truck had a manual pedal assembly with the rod for the z bar going through the floor when I switch my truck to an auto trans. You can use nice button head allen bolts and it will look clean.
