What fuel tank for my Duster?

[360Duster75]

Ok i have a 75 Duster 360 (running a 408 stoker and have no polution laws) and i need a fuel tank in it but not sure on what size as it doesnt have one now. I found on that is a 29 3/4" x 19 1/4" x 10 3/8" and has a 16 gallon cap. with 1 vent tube on the side (not sure what its for either) so is this the one i need? Or a different one

There are many companies out there that sell the reproduction tanks. Check E-bay for the best prices. I would just order one that is correct for the car. It should be the single vent version from '70-6. Many of those vendors have the senders, straps, and bolts too if you need them.
