ok..so I ordered everything on that list I posted except the leader hose since I had it already. it came to like 33 bucks plus shipping and was at my door in 2 days. It was everything that is offered in the airlift kit and the same stuff that onboardair.com offers on their site.
So far my total for my york is right at :
york: free
rotolock fittings: 30 bucks
3' leader hose: 44 bucks
pop off valve, check valve, intake filter: 33 bucks
Right at about 110 bucks so far. I still need brackets and a belt and I'm all set for air supply...Just need bags now!
