do you have an pro sheet in the center console or rear storage door? if so, list them all. if not, there are a few other ways. jack up the rear safely, and mark the driveshaft and tires. turn the driveshaft and count how many turns it takes to make one tire revolution. or, accel to 60mph in third gear if auto, 4th if 5 speed, and tell me your tire size and engine rpm (assuming the speedo and tach work)
