Model numbers for decks

[bo dawg 517]

Where can I get some different model #'s of 48" decks through the 70's? Looking for the spindles/housing/bearings numbers.

My 48 deck is 05-48ms01 (1980) but theres 3 different types of spindles/housings. 2 are 1980 - 1983 I know for sure. I just rebuilt 2 of them with extra parts I got from porkchop, (thank you). I like to have a matching set.

Oh and I had a couple helpers while I was working on them. But as typical helpers it was hard to keep them interested.
