97 Cutlass Supreme Strut Replacement

I'm getting ready to replace the struts on my 97 Cutlass Supreme SL with KYB's. The question is, how do I identify the Heavy Duty Suspension from the Standard Suspension ? Evidenty the front strut mounts are different, but how can I tell what I have ?

Thanks ............

Look at the rpo label in the trunk Fe1, 2 or 3 designates the suspension. Fe1 is std.

Thank You ! FE1 it is ! Don't run off too far, I'm sure there'll be more questions. As I told someone else, " With age doesn't always come wisdom " .

Its not the most fun job in the world.It hard so take your time.When you get done youll never want to do it again.

Well, at least there are no spring compressors needed on this one. I was able to tell it was Friday the 13th, though ! New brake pads also ended with rebuilt back calipers. Oh, the fun of it all .............. and I'm still not done.
