Generic Info packet from the GM Heritage Center archive is attached. 1SA is the "quick spec" in the dealer order guide. The info packet doesn't call it out the same way but since it is a Work Truck you have a pretty good idea of the content anyway.

Thanks for tapping in Keith.

I noticed that there were a large number of suspension RPOs, all LH or RH. Is my supposition correct or even close to the case?

Or is it just covering Berettas on up to K3500 springs?
