New member and owner/Case 580K identification

All, I bought a Case 580K last week and it needs some good general maintenance as well as some electrical repair. Before I buy some manuals I want to make sure I know what I have. I think its a Phase I 580K but have seen some info online that may lead to it being a Phase 3.

Here are some numbers from the Tags...

ROPS S/N 12203898
Engine Plate - 4-390
Engine Plate - A174025
Engine Plate - 44224890

Frame 580K Pin/No 17424833
Manual says for PN JJG0020000 and above
Wheels are stamped 1990
Gear shifter is in the floor

Im guessing the wheels and manual are from another loader and its a Phase I. Any idea what year?

I may post some more threads as I sort through this wiring nightmare. :Banghead

Thanks
