Just in case there are people still looking, I was able to place an order from Milford Power Equipment - Outdoor Power Equipment Sales, Service & Parts Since 1994 for the above stated part # $14.16 shipped. thank you OP
1979 Honda Z50
..and 1 Chihuahua
This cap fits the pre 2003 tw and xt350 tank. I read somewhere on my search that a Honda generator gas cap will fit the newer then 2002 tanks. I will try to find the posting and post back here
Turns out the thread I was referring to was one you started back In Dec 15'. Placerlode had replied that Honda power washer gas caps fit. Did you try that route?

To keep my original cap from rusting I just smear a little Vaseline on it, the whole metal part inside the tank. Also smear a little Vaseline on the seal if it is to hard to turn the cap.
So my cap came in, and it fits my xt350 tank perfectly. Thanks again OP
BUELL88 Thank you very much, I ordered one and its on my Tank now, It is very nice.
I will probably order one for my other Tw. just because I like it so much.
