LMM Segments OS 12628594 07.5

I have an odd ball here, I looked up the OS and Segments on GM TIS, I have a hard time finding the proper segments.

The segments I need I can only find in a 12617103 OS and they can't be swapped out. The ones that I am looking for are

Speedo 12628797 or 12617137
System 12643813,12628787 or 12617127

Thanks

I'm no help but as long as you have the correct OS base file you can just do a CAL flash and none of the segments will change. This doesn't help if you need to full flash for other reasons though.
