I have some too for all the same reasons. I still had wheel hop when I put them in though, so don't expect a cure from the air bags alone. Last summer I put in tubular lowers and adjustable uppers with new bushings, and I STILL have wheel hop, but it's better. I haven't had a chance to dial it all in yet, though...The Airlift 1000's I put in my 70 hardtop work great! MUCH nicer ride than the old air shocks I used 20 years ago. But they still allow me to lift the rear to where I want it.
I ran two air lines. The rest of the suspension is stock except for a nice pair of black gas shocks.
