IDave, the rear output with the built-in gear and roller bearing in the end is the part I'm looking for. #070-36 in specter's wonderful catalog. Mine is severely chafed and worn where the bushing from I think lo gear rides. Also, the splines are notched from wear about .080 near as I can tell. What exactly do you have?
3_puppies, the t/c I'm rebuilding is from my 66 fj40. Donor parts(all the gears really) are from a bit newer-unknown year. All looks the same except the gears are a darker metal color and the driveline flanges aren't notched out between each bolt hole-same pattern tho. Hope that's a decent explanation-still learning the lingo...
thanks all!
