I heard you were airing up...I am thinkin about airing none of mine, I cant bring myself to cut the Buick to do it "right" and the truck is an expense I don't care to spend...its just a $7k truck ....the passat I'd LOVE to do, but that'd be down the road. I'll probably sell all my air stuff and go ahead and wheel and tire the Buick. If you know anyone needing new, never used air ride stuff, I have a good bit ($900 worth...sell all for $600) Viair 325 comp, 4- 1/2 Blitzluft, and 4 -3/8 SMCs, 7 gallon tank, 4 2600 lb bags, 50' 1/2" line, and a box of fittings and more stuff I know I am forgetting.
