H22A4.... Where did you find this info on the lift difference and why would they build in different lifts (assuming the frame mounts are symetrical)? I really like the way your car sits and am looking for a similar stance for my 68 cuda but I had never heard of the lift difference. My OLD stock springs sit 1" lower on the passenger side already (because they are worn out :-D ). Also where did you order from that let you buy 2 left springs?
