Larger Hole Than Normal Master Cyl??
I am reassembling my 67 with a new firewall. It has a lager hole stamped in it at the master cylinder mounting area than original. I'm assuming its for a booster install, but i'm keeping it manual. What do most people use to block,seal the extra gap at the top of the mounting flange? The M/C will be replaced with a new one.
