Yes, I'm glad that you got away with your project for little money. I think I'd prefer to use an adapter plate so I wouldn't have to drill any more holes into the firewall.
I've seen one online but it says its for 1966 and up, and mine's a 1965.
I didn't drill any new holes in the car, If you read my thread you would know I modified the hydroboost mounting plate to fit the original car mounting studs (4 of them) you can spend $500-$600 on a bolt on hydroboost, but I did the same thing with a little work (took about a half a day) and a whole lot smaller amount of money
