Currently running an SSR keyless cap obtained on ebay,,,fit up was more that easy,,,,no leaks,,,installed a Pro-Bolt bolt cap surround set also,,in black to match the cap,,,,,purchased another one of ebay (I bid and won it for 10 bucks USD) a PSR 1/4 turn cap ,,not tried to fit it as of yet,,,I think I like the SSR better as it's a "flush fit" however,,,
