Works just like a see saw. >Scott >www.turbovans.com Yes, but the longer the lower section is, the less leverage the top section (the one you push) has on it, making the shifts more & more difficult as the leverage decreases.

As to the airshift, I begin to suspect that my mechanic helper is confusing manual shifts with dragracing auto shifters. -- Andrew Grebneff Dunedin New Zealand Fossil preparator Seashell, Macintosh, VW/Toyota van nut � Opinions stated are mine, not those of Otago University "There is water at the bottom of the ocean" - Talking Heads
