60-62 X Frame Rear tank

[60 Apache Shorty]

Hi
Has any had any luck finding another vehicles gas tank that is rear mount, rear fill fuel tank that fits on these trucks. I have found the Spectra Fuel Tank GM15C fits back there, and the fuel fill can be orientated to the rear but it hangs so low. I know on the 63-66 it looks like some of the retro Camaro tanks fit but appears to be too wide for the 60-62. I also really am looking to have a in tank fuel pump if possible.

I know there are some aftermarket sites that do make custom tanks for these frames but checking if there are more affordable options out there.
