Marty,

Here is a link to a Moog Part number (8492B) that cross references to the original GM Part# 38588389. Specifications indicate it will fit your requirement (even though not listed in the vehicle application list). If you scroll down, it gives a long list of cross referenced manufacturer and part numbers that will fit your application (including the NAPA 262-1016).

After a short web search of a couple of the cross referenced part numbers, here is a link (not mine) to a seller with 3 sets for sale on eBay at a very reasonable price:

King Pin Set

Hope this is of some help in your search. headscratch

Let us know how it turns out. thumbs_up
