OK,
Here are the PN#'s for the CPS and you can see there is a difference between the years. However, a CPS that is for a 97 will function just fine in a 96. The only difference between the two is what the pin material is made of. Some say using a CPS for the wrong year can lead to corrosion between the two different metallurgys. But as far as function goes, they are interchangable.
