Air ride on my 66

[KandyOrangeZ]

Picked up a 66 t bird about 6 months ago. Looking to bag it. I see ridetech makes a leaf over kit. Has anyone used it? How much does that kit lower the Bird? I'm looking to get it as close to the ground when all the way down, suggestions?!!

Hey everyone. Currently looking at air ride options for my 1966 bird. Has anyone here run a 4 link? If so What brand? What would you suggest?
