Ok, I brought the gears in from the garage. The pinion has numbers stamped into it on the gear end. On the end tword the spline there is a number 5 written on it in green paint marker and an orange dash. The ring gear has a number 5 on it also as well as a number 23 but the difference with these is that these were put on before the
heat treatment of the gears. Screw it. I'm installing ...
