Pacer/Pony parts interchangeability

[bcsawyer]

II have an old Pacer that I tend my garden with and this spring I will probably use it to cultivate tobacco. (I may use a 3pt cultivator behind our 135 or 35). The tractor is worn but serviceable and used parts for it seem to be hard to find. Pony parts are much easier to find, so I was wondering what I can use and what I can't. I know the engines are different but does anybody have a list of what will interchange? Also, does anyone know where I can find a John Blue fertilizer distributor for it? Thanks, Wesley
