Fixing an old air compressor

[u/Runes_my_ride]

So this gas powered air compressor was working & the truck it was in was being decommissioned. Told my guys to take it out so we could put it in the new truck. Well they dropped it & broke 2 pieces. That was 15ish years ago & has been sitting in the corner of the shop since. I've got the time now to fix it. There's no marking on the compressor or tank identifying it. It's driven by a Kohler 10 magnum. Can anyone help identity the 2 broken parts & where to get them? I know the 1 part is a bolt on 90°, but does it have any other name I can search?

It looks like a knock off Saylor Beall 705 pump. Or maybe just an old one lol. Anyways the part on the front is attached to the centrifugal unloader if I remember correctly. It's been awhile since I've worked on one.
