can some please help me if they have any old diff's or gearbox parts the input shaft ie cup to the shaft from the diff has broke on mine

You might be better off getting a whole new diff, unless you can find a broken one? I've got one for sale but you'd have to get it welded.

i only need the input cup that goes in the diff the rest of the gearbox and diff are fine i will put a pic up of it later
