They are installed, but parts of the car (fenders, hood, core support, radiator, etc) are not installed as yet, so ride height not finalized... Since I had them match all the physical specifications of the factory EY spring I sent them, I think I will be happy with them... certainly more happy than buying OTS springs which perhaps match the ride height (maybe), but none of the other physical specifications...
PS. I do have the physical characteristics listed herein (0.610” wire diameter, 8.125 Total coils, Inside Diameter 3.675”,
Free, or static, Length 15.00” +/-, Load Rate 370#/in). .. and here is a photo of the one original EY spring, along with the pair from CSS... (one of my original EY springs had a broken coil necessitating the new ones).
