Yes, any alternative matrix variations are highly welcome. Verifications of already existing entries as well, you would make sure that your drive is working as we need it to be. Thank you.
Yes, I am reasonably confident I can repair at least one of the drives. The PX-W5224TA (on the supported list) is just jammed and might need a belt, gear, or lubrication (tray doesn't eject). Worst case, I can manually bypass the tray. I do have 3D printers if I need to fabricate a part. The PX-W2410TA (not on the supported list) makes grinding noises when trying to read a disc (belt or gear slipping?). Regardless, both sound like physical issues and I can probably deal with those even if it means buying another parts drive.
The IDU disc is Fall 2013 PS3 IDU 4.46. I picked it up at the flea market last weekend for a couple bucks and I was surprised to find it isn't already dumped. With many of the other undumped discs listed as "purchased" by another user and most IDU discs going for $50 and up, I thought I'd save everyone the trouble/expense. 
Thanks again. I will follow the guides to the letter on my next day off!
