Will a b/e-fuel tank fit with a modified a-body pan?

Decided I wanted more fuel capacity in my 1973 Duster as the thirsty little
Motor I plan to swap in eventually will need some mileage between fill ups. The previous owner removed the tank and drop down trunk section due to heavy rust out. I figured since the pan is gone, I might be able to use a 1966-1974 b-e-body gas tank or even an aftermarket one that will get me closer to 19-20 gallons of capacity. Reason for a stock style tank is I can still try to use the side fill up on the driver side. Any info on fuel tank swaps?

You might be able to use a Challenger tank, but you would have to swap the fill tube to the passenger side. Cuda tanks have a rear fill tube, but the tube would end up in the tail panel of your Duster. A friend of mine used a Mustang tank in a Duster. I fit well, but the gas cap being in the middle of the tail panel just looked odd. I had a custom aluminum tank with baffles made for my 70 Duster when I was gonna swap to a 5.7 Hemi. I cut out the spare tire well and was going to make the trunk floor flat and bolt it up with longer straps hooked to bolts in the reinforced rear cross member. Sold the Hemi and never put the tank in! It's too heavy to ship, or I'd sell it. It's a 25 gallon tank. You might try to find an old 68-70 Roadrunner tank to mock up and see if that would work. Might be too long? Don't know? Good luck with it.
 
Thanks guys. I was referring body types as a general info, knowing some of those models had driverside fill holes. I’m thinking 1968 Charger or Challenger model might work. Unfortunately I don’t have either tank or cores to verify at the moment.
 
Consider one from an '88ish Jeep Cherokee.
20 gallons, driver's side fill.
In-tank electric fuel pump, 70-90 psi (depending on manufacturer), 50ish gph, 3/8 line with a return fitting.
The sender's ohm readings are similar to stock Mopar, but get this, they are reversed. So your gauge will read backwards- empty when it reads full, full when it reads empty. Easy to turn an "E" into an "F" and vice versa on your gauge if you feel so inclined...
Look it up on Rock Auto, tank dimensions and various pump specs are listed under "more information"; maybe it'll work out for you- it's something I've considered in the past but never acted on.
 
That does sound like a good idea. My friend suggested looking into ranchero 1964 tank as it has a larger capacity and also side fill.
