Brian,
I don't remeber exactly how a Dina seat is, but most air ride seats are different from Harry's and mine (gotta love a Setra!), and have a small silver round knob that you pull on to let air out and push on to put air in! Also you'll find most air ride seats use a small air bag as oppsoed to a cylinder. Look all around the seat on the sides and front and you should find a valve or button to adjsut the air in it! BK ;D
:) ;) :D It's gonna be a Blast at the "TN Fall Bus Bash" at Knuckle's check out the "TN Fall Bus Bash" Thread to see what all we got planned! ;D :o ::)
