Steam punk gas cap .
Hey guys . I saw this gas cap the other day on a custom website and thought how cool It looked a little steam punkish maybe ( they do a bunch of other designs also ) The thread size Is 1.75 wide outside diameter and the threads are 4 course threads per inch, anybody know If this would fit our tanks ? Iv tried searching for triumph gas tank thread size but had no luck . I reached out to the store that sells these but all they did was send me the thread size .
