I've made it here
 

Hi there! I have a 49 chevy truck that has been in the works for quite sometime now. It has a 74 nova front clip and rear end on it. I'm ready to install a gas tank or fuel cell inbetween the rear portion of the frame rails and need some advise. I don't want to go out and spend an arm and a leg for a new tank or cell so my question to you is what tank fits inside the rails without major modification that holds a fair amount of gas for long rod runs? {12-20 gallons} Thanks for any information on this matter.
