I just cleaned my Rave valves on my 2000 GTX and noticed that both the O-rings and Supporting Ring were located on the underside of the guillotine valve. After consulting my repair manual, it appears that there should be a o-ring on the underside of the guillotine where you side it into the base and then on the top side inside the bellows along with the support ring going on top of the o-ring. My question is. The support ring is concave. Does it go concave down or up to meet the inside spring that resides under the bellows. Thanks
