I've compared them compressed and uncompressed, the difference is 4", I even tried fitting them, got them on but the ride height was huge! Lowered off stands and wheels didn't move! Strut end was forced out of hub retainer till they touched the driveshaft! There are paint marks on the old ones white, yellow and blue, got some replacements with white, white and yellow these the ones that I tried fitting! Bought some new ones, un compressed the replacement ones and they the same, compared to the old that is 4" difference! Parts supplier is making some calls tomorrow , I'm gonna ring seat, find out if a mod has been missed! I wish!
