I have recently purchased a 1986 w126 burgundy 300SDL and I’ve been fixing things over and over and I’m near towards the end of the list of things I need to get done to get it on the road. I’m trying to replace the rear springs and shocks. I already have the brand new springs, but I need the right specific thickness of rubber bushings to order so the car won’t be higher up than intended, which would prevent me from getting an alignment. Very confused, I’ve had a w123 before and loved it, I have sum experience with older Mercedes. But I have no idea which of website I should go onto to look up the different thicknesses. Or shop for them anybody have any ideas of sum websites or sources to find the right thickness?
