Swapping 1303 to 1302

The upper bearings do not affect the ride height; however, the upper spring perch (cup) does. Notice #21 on the left (1302) and #38 on the right (1303). The 1303 perch will raise the car about 1" and they are interchangable, consequently the 1302 perch will lower the car when used with a 1303 strut assembly.
