Default CCM the same?

Will a CCM service number 16153090 work as a replacement for service number 16155502? All I know is that they're both off a 91. Thanks.

A correct CCM would likely have both numbers on the label. 16153090 is likely the ACD/GM original build and it would have a "SERV NO" 16155502 also. 16153090 isn't a "service number".
