Suzuki 2 Strokes

Hi folks!
New here, and looking to scrounge together some bits and pieces, specifically a cap for a Titan gas tank.
Any help would be greatly appreciated!
Thanks!

I have a tank (not sure what year), that has the "cross-pin" that the latch on the cap grabs on to, offset to the right of the filler hole (when seated on the bike).
I found a cap. but it is oriented for a "cross-pin" that is situated directly behind the filler hole, so it's not working.
Does this make sense?
If so, I need to find a cap for the offset version. Any idea what year that would be?
Thanks!

Quick update.
I found another tank, that has the cap l need included! The chrome and seal are very rough, but after a good soaking with PB Blaster, I managed to get it all apart for cleanup.
Now, I have an extra Titan tank if anyone's looking...
