GM Tech (Cam) :

yes, most times the part number on the module will not match due to change ups.

JACUSTOMER-z73n9i14- :

so it is the right part & is that the current part number i need to be asking for?

GM Tech (Cam) :

It may change up again, but ask for that part number and if it does change up, they will automatically get it.
