I ordered shorter valve stems to go with my Arc8s and they've just arrived. I'm out of town and can't test fit them but my fiancÚ sent a pic to me. They're the part referenced in this thread (http://www.zpost.com/forums/showthre...highlight=tpms
) but the screw at the bottom looks larger than what came stock and I'm concerned that it's too big for the slot in the TPMS and won't fit. I've attached pictures of my tpms and the new stems. Any TPMS gurus know for sure?
