Some interesting questions...

I'm nowhere near as clear on the GMC parts books but it looks like the D45 shoes part no 2405962 also fit D44 axles all the way back to '35.

Same part number shows for 58-59 w/ posi trac in the Chevrolet parts book:

I've never seen a posi rear in a Chevy truck so this helps confirm for me that Chevy used a Dana 45 if customer ordered a posi.

Looks like a cool find!
