Hi,
I am beginning the process to adapt a more modern Getrag 265 5 speed transmission to my 113. Currently I am having an adaptor plate made and wanted to make an adaptor bushing for the pilot on hte imput shaft as well. I purchased a bady rusted 4 speed to use for measurement purposes but unfortunatly I need the diameter of the pilot area of the input shaft and that is too rusty to trust the measurement.
Does anyone have a transmission they can measure or the spec somewhere?
