thnx larry, i wanna get them and i would run the air lines seperate, not hard to add same psi to two different lines. until the time comes to do some passes at a track a would use it for ride height, or simply to keep the car lvl when me and the friends are cruising. a buddy of mine had them on his 66 chevelle and i was talking to him about em today. good luck on the upgrades though! hope it all works out well at the track. the better timeslips equal better bragging rights!!
