Flush-mount saddle tank doors?

[davepl]

I searched around the threads I could find on fuel filler doors, but I get the feeling I'm missing a lot of assumed information, so maybe it's worth bringing up again:

I have a Longhorn that has dual aux tanks, and hence, dual aux tank doors. They're not really the most attractive things in the world, and I'd like to keep the tanks but downplay the doors.

I was thinking about having a bodyshop graft in flush-mount, body-color square doors, if I could find a nice donor. But since I have one on each side, unless they're truly symmetrical that might be problematic flipping them over side to side.

I guess that's sort of my long-winded way of saying: I'm sure others have solved this before, so instead of reinventing the wheel, is there a kit available? Or a common donor vehicle that people harvest doors from?

As always, a picture or two is worth a thousand words!

Just to be clear, my goal is to either hide them or at least get them body-color, not some billet replacement. And it's an otherwise stock restoration, so something that would pass for period-correct is best for me!

Thanks for the help!
