Air suspension on '73 dart sport?

Yes you can lower it. If you lower it all the way down, you will damage the shocks. Check how much you have now with a tire gauge and go from there.
Thanks! I have a tire gauge so I'll check the pressure out. What do you think the bandwith in PSI is? So I can get an estimate of how low I might go in lowering the car by releasing air from the shocks.

Sorry if I'm ging too much into detail.. I'm new to the world of classics and mopars in particular. Trying hard to learn though.
