My son had bought me maxspeedingrod coilovers (adjustable) see pic. I'm at a loss because I'm doing this by myself this is my first time I got the front ones in those are the hardest ones because it took me three days mind you I had to go and buy the tensioner tool to get  the coil out and I guess my question to you is this ,as you can see in the pictures the rear ones did not come assembled the coil is not on it and then there's a little piece that goes I don't know which way that goes on the shock o sorbet and if you could please help me to properly put it together before I go and put on  the car in the rear and also I was wondering because Mustang has divorced  Shock and coil in both front and back do I remove the coil since there's one on these or do I leave the coil please help! Also You have taught me a lot through the years so thank you Scotty!!!
