Hello,
I am putting a new driver and passenger seat into my RTS. I got a great deal on Craigslist on two new leather racing seats like for a sports car. These have built in slide rails on them for forward and backward positioning. Since the RTS is a transit bus, I also bought two brand new National 95 air ride pedestals. These come with no adjustment valves to raise and lower the seating position. The dealer wants $40 per valve to sell me valves, but he said I could probably do better elsewhere to buy these parts. He didn't have a picture of his product, and I don't really know what valve I need. I suspect I need a valve that has 3 positions: center off and one position on each side of center. Then, I would push the lever one way to make the seat go up, and the other way to make the seat go down. When the seat is in the desired location, I would return the lever to the center position.
I found some valves that might work at this url, but I can't figure from the description if they will do what I want.

They also appear to be more expensive than $40, but my goal is to determine what kind of valve I need, and then I can look for a better price.
The seats pedestals use a 1/4" diameter air hose.
Any ideas?
Thanks,
Kevin
