Best I remember all the fiat tractors that size had the utility tractor frame meaning a set of bolt holes in front of the front axle and another behind and then nothing much to bolt to at the bell housing. so it would have to be attached at the rear axle. so your needing a sub frame that runs from the rear axle to the front attachment points.
Can you do any work yourself or do know someone that can?
A sub frame to fit will cost about as much as a used fel.
I have seen the new mid mount smaller loaders at different sites and auctions for 600 to 1500. But they have not mounting brackets or methods of attachment.
If you can build a subframe then alot of loaders will attach to the tractor.
so look European if you want new. Fiat is Case New Holland and other brands but they wont all fit.

Depends what you want to pay ..I would be looking at wreckers ? Good tractor but you will have a tough job in north america !
Try sourcing in Canada, particularly Quebec. Those tractors were very popular there and I see plenty of them in the eastern townships between Vermont and Montreal.
I have a 100 90 DT with the loader. Awesome machine.
