Help me identify this Michigan loader model type

[mask]

Hi, I am curious what model this Michigan heavy loader could be?

Here you can see an image gallery with a few images of it:

I'd say maybe a 75 ? But in order to be certain I'm asking you. Where on this machine would I find the type plate, serial number or something to identify it properly. All them stickers have come off.

Appreciate your help

I would guess 85a

Can you get model and serial numbers off transmission, convertor, axles any of that would help to identify the machine,also there should be a serial number stamped in the frame somewhere.
