Yes the '51 Henry J and those '51s which were reserialed as '52 Vagabonds used an Autolite starter. All Corsair and Corsair Deluxe models used a Delco Remy unit and they are not interchangeable as they use a different clutch housing and different wiring. The wires from the starter button to the solenoid on the Delco Unit are 12 gauge and need to be. The one on the Autolight is 14 gauge. The starter button is different too - the one used on the Autolite is cheap with small gauged contacts which ground the solenoid whereas the starter button for the Delco equipped cars is heavier gauged and has two terminals on it because it supplies a hot wire from the ignition switch to the solenoid instead of grounding it. Of course there are ebay sellers and some KF parts vendors who are unaware and assume "one size fits all" on anything for the Henry J so beware. I'm sure there were some surprises from people who purchased parts listed for "'51 - '53 Henry J..." and found out otherwise.
