Mocking Up Firewall for Master Cylinder Studs

I changed my 1967 firewall to a two hole but cutting and welding the studs. Take the piece you cut out to get your bearing on where it should go. I measured two holes level between the two studs on each side and drilled, no big deal. then I cut a center hole by grabbing the next size up hole saw (for adjust-ability), and the extra metal on the flange covers it well.

there are a few pics in my build thread and some more here: http://1967barracuda.shutterfly.com/pictures/451
