What make/model gas tank cap is interchangeable with the cap from my '82 Avanti?

We purchased a Stant gas cap from Betty Booth at Nostalgic Motors (800)-AVANTIX or http://www.avantiparts.net/. Unfortunately, the cap appears to have no product identification number.

On my '81 I matched up a "screw" style cap with one at an auto parts store. My '81 needs the newer style, threaded, screw on cap.

I had to modify it by grinding off the twist tabs, so as to allow the car door flap to fully close.

Later, I did one better, and bought a basic old style smoothie "chrome" cap. All I was after was the shiny part, so the application didn't matter.... kind of resembles a baby moon hub cap.... then, I carefully disassembled/destroyed it, saving only that shiny top.

I then epoxied this shiny top onto my existing cap, after trial fitting and plastic filing/grinding, to make sure the new modified cap allowed my door flap to fully close. Looks cool, like an old style cap on the modern tank end.

I found a perfect fit at the local Advance Auto. For future reference, it is part #6817, manufactured by Cooling Systems Technologies. It "clicks" when snug, so you can turn it to a position where there is no interference between the tabs and the fuel compartment door.

By the way, Joe, your car is the spittin' image of mine except for the wheels. I went with original Studebaker Avanti reproduction wheel covers. Not as sporty, but real easy to keep clean!
