Thanks Marc, I have found them on GM SupplyPower.
Bill, something interest here. firstly, GM Buulletin 5143 request "All PRRs need to have Drill Deep Worksheet and Read Across Matrix completed and attached to the PRR for closure." I attached 2 related documents below. Secondly, we have never did it before and SQE closed the PRR without any questions. It seems some of GM SQEs do NOT know their own requirements.
The problem was discovered by our TS auditor, even GM request and GM does not know they request, we have to do it.
This is BIG 3!
