I have a "46" PU with a later 235 and possibly a later four speed transmission as well. I have lost the gear that threads on to the side of the transmission that drives the speedometer cable.
I want to know what I should be looking for in a replacement. Will gears from a three-speed fit on my four-speed? Are there differences between different years? How do I tell what year my transmission is?
ALSO: there is a grease zerk on the top of the transmission. What for? Am I supposed to fill the trans. with grease?
