it will fit but wont work. the starters have different drive gears to fit the flywheels. The teeth are different to fit the different flywheels. 216 has 139 teeth, 261 has 162 teeth on the flywheel
okay. Thanks. Can you change the drive gear on the 261 starter to the one off the 216 starter? Or is it not worth the effort.
It's a 6v or 12v thing, they changed in 1955 to 12v. The starter is completely different, you can't put any of the 12v starter parts in the 6v starter, or vise versa. Sorry. But if you put the 261 flywheel in the car, you can use the starter too.
