I'm using one of Rick's tank's in mine. It's mounted where the battery would be and is square outside but round inside. Basically a tank inside a tank. I think mine was the second tank that Rick built. It fit nice, it has threaded holes at all four corners on the bottom for mounting which we basically made brackets that bolted to those then to the inner fender and core support. They said that they talked to a well respected circle track guy when they designed it for the correct baffling/breathing etc. The car was just mocked up so far and is at the paint shop now completely disassembled, so as far as functionality I'm just taking there word that it will work. I'll have that answer in a few months when it's finally finished.
