Need pictures of bedside fillet doors, even in progress

[custom10nut]

I'm about to start my tank relocation project on my truck.
I plan to use a side fill tank and have the filler door on the bed side behind the wheel opening.
I know many have done this, so I'm hoping there are a bunch of pictures, showing where to cut for the filler tube, and where it come up into the bed.
I scored a filler tube cover out of a newer Blazer, so I won't have to fabricate that to make it look right.
I'll post some pictures of what I have and where I plan on putting them to get, some advice from the experts
