Zetor 5245 Loader Info & Parts

I'm hoping someone maybe able to help me here. I have a 5245 model Zetor. The problem I'm having is, the joy stick that controls the front loader bucket is shot. But I can't find any info on the unit what so ever, so i can get the replacement part that i need. On the arms of the loader attachment it say's Zetor and I have all the manuals for this unit and there is no mention of the loader attachment at all. Any help would be appreciated

you can joy stick control levers from any agri store, they just need hyd and electric controls

Alright, Thank you
