I can't think of a part on a loader that would need brand specific replacement. With some welding to do a repair to the steel or replace pins/bushing that are available at a tractor supply and a good Hydraulic shop you should be able repair or replace anything that could wear or be damaged on your loader.
Do you have specific parts you think you may need to replace someday that would be brand specific?
If you run into that I am sure someone here could help you source them or cross them into another brand.
