It appears that no one is making a gas tank for these trucks. If someone know of a supplier for a gas tank let me know. 81 4X4 short bed. Will the gas tank from an 84 up work? Making bracket to make a latter one fit isn't a problem.

 

I have a 1980 that I am working on getting it back up and going. Not sure where but I came across a post that had a link to this tank from amazon. If you look at the reviews someone even mentions that i works in the 79-83 year model range.

It'd be difficult getting one of those

 

Good to know. Thanks.
