I was always amazed about the gas filler located in the “early” Pantera!
as I was looking for a solution I do like I came across a “Cobra” stile filler that wouldn’t look huge for the sail panel it will be mounted on / in!
There are many different ways the factory fuel filler location) which wasn’t even used) looks :
some have a egg shape, some have a round indentation/patched up hole with spot welds…
I my case it’s a 1.5” hole that has a patch on the inside and 3 spot welds on the outside.
