Autozone asked if I have the "normal" suspension or stiff, I told him I have an 88 GXL with 5 lug rims, so the bigger of the 2 sets of pads, he told me to find out for sure, Im gettin them tomorrow morning, so help me out here

 

You've got "stiff". The difference in suspension really only has to do with whether you have 4 piston brakes or not. If you're got the 4-pots, you've got the "stiff".
