57-60 F100-250 rear fuel tanks?

I want to remove the fuel tank from behind my seat and do a rear mounted tank. I know LMC sells a rear tank, but it's pretty pricey. I have not got my bed off yet to do some measuring,so I ask y'all that have done it, what did you use?

Any help,advice,pics,and build threads would be much appreciated.

 

I have seen many use a mustang tank flush mounted in the bed.

 

Mustang tanks are reasonable and should fit behind the rear axle under the frame. Try Bob's Mustang Parts

 

Thank you! This site kicks butt! Great people here!

 

Dallas mustang has them pretty cheap.

 

Isn't NPD near you? Order your tank through them and when you do ask for a "spectra" they are made in canada and a hell of a lot better then the over seas tanks.
