    Are Hudson speedometer cables the same for the standard transmissions. Meaning will a speedometer cable from a 3 speed hornet work on a 3 speed truck. I know the speedometers are totally different, but can the actual cable inter change. Thanks

    It's not that simple, if you want your speedometer to read correctly. The drive gear on the end of the cable has to be correct for the rear axle ratio and for the speedometer used. The pre-1951 (1948-50 A series) speedometers required a gear that ran twice the rpms of the later 1951-54 Speedometers. I believe the 1941-47 Hudsons (including the trucks) used the faster geared cables like the 48-50 Stepdowns.

    While we're on the speedo cable topic, what's the best lube for these cables?

    No, you need the gear from a Hydramatic that came from a car with the same rear axle ratio as the car you have. What rear axle ratio do you have? If you changed from 3 speed to Hydramatic, did you also change the rear end?

    These are the gears I have. The one on the left (longer one) fits my cable and spins the cable. It does not seem to fit in the transmission. It sticks out too far. Is there more to installing the gear than just dropping it in, maybe I am missing the trick to getting the gear to seat properly

    The long shaft gear looks like the ones used in the 1941-early 1952 Hudson trans.
    Short one looks like those used in the Borg warner trans. used by Hudson from 1952-56+

    Any other opinions??

    The transmission is a 2 lever T86e. When I got it I was told it came from a 54 Hornet. Unfortunately it came with the gear, but not a cable. The cable I have is from a 46 super six with a drivemaster transmission. So maybe I need a different cable?
