on the part # of the springs, the last two numbers are what we use to tell us if it is a soft or stiff spring. fronts range from 13 to 19 (19 being stiffest) and on the back it's like 53 to 60 ( 60 being stiffest) there should be a white tag with the part# on each spring if yours are stock. you might even find different numbers side to side because of the gas tank on the passenger side
2dr's generally have 13 to 16 front and 53 to 56 in back, 4dr will have 15 to 19 front and 56 to 60 in back
hope this helps.
