Guys aren't using the reamer without sending out $10 are they?
I remember not being confident that it was actually a proper fit. It seemed that it was sitting on a common edge along the taper as opposed to have a real internal mating surface as the 2500 TRE would rock in the hole. It's why i tried to make sure there was a wide path to carry the load when I reamed the knuckle (and took out too much material). To be honest I was workin on the TB for 16+ hrs when i was doing it so my memory is admittedly hazy.
I have to take it apart tomorrow and I still have the stock tie rod ends. I'll measure the taper on both when I have it apart and take some pics. The taper and the major and minor diameters would need to be the same. I never measured it originally, just went off the info in the original thread. Better we're safe than sorry. It is steering we're messing with after all.
