Welger AP71 parts wanted

I'm fixing up an old Welger AP71 small, square baler.

 

Parts in this part of the world are hard to find at a reasonable price, so I'm reaching out to the Haytalk community to see if anyone is dismantling an AP71 and is willing to sell parts or could recommend a good parts seller.

 

I have a German parts book.

 

Some of the parts I'm after are :

 

56.11.105 PTO spline

56.73.04 clutch plate (4 required)

58.60.07 part of the clutch assy (german name is Mitnehmer)

disc brake

disc brake pads

0726.10 roller (part of the bale length assy)

needle

 

 

Any help or suggestions are most welcome.
