I am going to be putting in KYB struts all around, Eibachs Pro's, & some sort of spacer to lift the rear about a 1/2" between the spring and the strut (also need direction with this if anyone can). Also, I am going to be replacing the upper bearing mounts on the front as well, part #54610 (driver side is bad). My question is, from looking at the picture below, I can't tell if I should also replace part #'s: 54633, 54626A/55326B, 54623A, 54620, or 54612! Also, do I need to replace anything on the rear, or is it all okay to use again? I am getting everything through LowSonoma, I just need to figure out what to get. TIA!
