Vick,
The tank is a 1st Gen camaro/firebird 18 gallon tank. It is supported with custom bent straps I made. It is pretty wide but it fits. The exhaust pipes took some fancy bending to get over the axle and around the sides of the tank but it works well. The fuel bung was cut from the original and installed using some 2 inch rubber hose and clamps. The anti-squeak strips were cut from some tar paper from a local building site. Glad you like our efforts. We are happy with the way it is turning out also.
