Years ago I ran across a guy with a new hydraulic cylinder that looked like it would work just dandy as a toplink. I bought it with the idea of finding a remote hydraulic valve for my 850. Never did and now I don't have the tractor. Reply here or shoot me an email if you have any interest and I'll get you some pics and we can discuss price. I don't know the travel distance of the cylinder but I can measure the compressed length and you can figure from there.
