Phil,

Take a look at this previous thread on the subject.

Member "bouymaker" provided some detailed original and replacement GM part numbers along with the corresponding "AC Catalog" information in his reply post.

I just did a quick check on eBay and saw several NOS GM# 5647228 items being offered for sale.

Hope this helps out.

Dan
