im re doing the air ride on my 62 lincoln. The setup is about 15 years old. I was running 8 valves all 1/2 inch with 10 gallons of air and 4 compressors. I’m going to 12 gallons of air 3/8 line and the accuair switch speed. I’m going from a fast bag setup to something a little slower and something with less leaks. I ran hardlines in the trunk and all interior through the passenger cabin. New slam specialties bags and I’m redoing my 4 link. I’ll post pics as I go. I’m almost done and so far so good.
