First off, a HUGE thanks to OrrieG

for recognizing the bottom plates and helping me get GM (left in photo) parts for the rear 3/4 ton axle. I believe he has it correct that the one on the right is likely a NAPCO casting, one off of the original GM. They are identical except the GM is much better material as evidenced by the washer indents on the NAPCO casting that has an all around rougher material look and finish. They also bear different part numbers.
I have posted a second photo of the Warn lockouts that came with the 3/4 ton axles after polishing. WOW!
