I have a 93 SC300 which we bought a few months ago. The car seems to have been lowered and looks nice on stanced 19-inch wheels. I have a bad driver rear strut (leaking oil and clunking on even tiny bumps). Also tough to keep the car on the ground above 75 mph. Currently, it has Tokico blue struts on the back, but since the car is likely not stock height, I'm not sure how to order replacements for the rear. Any advice? Would there be a number on the outside, if I can clean off the gunk? Certain measurements to take? Thanks in advance.
