1972 gmc 3/4 ton gas tank relocation

[onebad8.1]

Hello I'm working on a 72 3/4 ton and want to put some after market seats in it but I will need to relocate the gas tank what's the best location and gallon size I should look in to? Thanks for any help

I've seen the tank put where the spare tire usually goes and also understand that a GMT400 Tahoe tank will fit that space.Search You Tube.

 

This might point you in the right direction....

The same era Blazer fuel tank will go right in where the spare originally went.

As said the blazer tank is a good retro. The creative guys turn one of the rear markers into a fuel filler door
