I have a fun one for yall, I recently traded for a Ax15 2wd out of a dodge dakota. My Comanche uses a Mechical speedometer and The tail housing has a spot that I originally had thought was a freeze plug of sorts that I could pop out for my speedo gear assembly but that part is just apart of the cast IE the pictures. Milling and tapping that hole is no big deal but for the speedo's "Pinion gear" I assume, I have no idea where I would buy or locate said part. It there is a spot on the main shaft to hold it place with a slot and two lock ring slots. Any help would be so Appreciated!
