Hi Dave,
You Might be better of contacting eagle machinery,

A andyathome in Australia, bought one it was missing the front fenders, he contacted eagle, with in a week he had the parts, latter on he had same problems with the rear diff,
here what he posted on a different forum about the rear diff problem,
heard a clicking noise in rear diff so I pulled it apart again( after checking it when I first got it).
not good! input shaft bearing completely toast. also found wear in the casting for the diff lock lever , like the casting wasn't big enough to take the complete movement of the arm.
had a bit of a think and also noticed in the casting of the axial tubes there looked like a bearing on the axial was missing?
contacted manufacture , (cant complain about their service) a new gear drive input shaft and axial was posted ,I fitted two tamyia bearings into axial housing , put about two mm of shims in to main diff gear bearing housing .
put it all back together again and perfect.
Ive probably put 25 plus batteries thru the loader so maybe its just natural wear , not too sure on that.
will pull apart in another 10 batteries and check them again.
Regards Cameron.
