Need a gas tank

[C.K.]

I need the rear tank out of an 88 f350 4 door dually. Any idea what size tank that was. I have found a few different sizes. The truck has a 460/c6, and is 2wd . If that helps any.

Also does it matter what size I put in? I was thinking about just putting in the biggest one that will fit. I'm guessing as long as I have the right sending unit/ pump for the tank I should be fine.

If anyone knows where to get a bed or good body parts for an old Ford that would be great.

I think it is a 19 gallon tank, I have heard of ppl putting in a 33g tank from a bronco but you will not be able to have your spare under the truck.
I think there where some write ups about it on
