Ok, thanks for pics, they tell the story...this is a GL model thing....I've seen that type and NO way are those suckers gonna fit - too long. But as LRCXed, mentions, a 90 degree job should fit nicely, I've only seen them in the sissy size for lawnmowers and such. I will check your links and at the dealer. Thanks for the ideas!
BTW, are the CX petcocks the sissy size too - 1/4" or something?

And what's with the rivets on the petcock flange? Is this not meant to be rebuildable?
