Bed fill or Side fill - picture request

[runpasthefence]

Hey guys, I'm fixin' to start tackling my LQ4 swap in my 69' short fleet and I've decided to hit the fuel issue first.

I'm going to order an ECE unit, but am undecided on where to locate the fill. I originally planned doing a bed fill, but I'll be using the truck as a truck so I'm considering all alternatives.

I've seen the threads on the tail light and side marker mods, which are awesome, I'd just like to see what else is out there and be able to compare directly.

Thanks in advance!
