Mark, the booster is for a 1980's Corvette, it was a left over from my brake system on the 59'. I decided to use a hydrobooster on the 59' as my cam doesn't produce enough vacuum. The vacuum booster was a pretty easy install, I made a template to avoid cutting the firewall any more than it had been already. As I said I added a backing plate inside the firewall to add more strength to the area.

These are a couple of boosters I was considering on using, both are small enough to not overcrowd the engine compartment.
