Grade C Head Gasket New part number

[03_DMAX]

Anybody know the new grade c head gasket part number.

I come up with 12637785 and 12637788 are these the right part numbers?

Coming up on gmpartsdirect as only $25 ?

Yes, those are the correct part numbers. Just installed mine last night. That is the NEW GM part number. Sure beats the 90-120 price

Whats so different about them that they are 1/4 of the price?
