That would be the correct starter for the 49 CJ3A. Also the same setup was used in the pickups/wagons/jeepsters for that year. What you referred to as a solenoid on that starter isn't, it's just a switch. For the 3A setup the flywheel ring gear should have 124-teeth. If the 2A flywheel has a different tooth count then it won't be as easy as just moving the starter. Take a close look at the bell housings between the two setups - not sure if there were differences between the 2A and 3A. What can definitely work, although it will require work, would be to take the transmission off of both engine assemblies, swap the flywheels and rear engine plates, and then put the 2A transmission assembly on the 3A engine. Of if you want to use the 3A transmission swap the bellhousings as well.
But if the flywheel ring gear on both the 2A and 3A have the same number of teeth and the diameter of the ring gear is the same there's a decent chance all you'll need to do is swap in the 2A starter on the 3A engine setup, or at the the worst swap bellhousings to allow the use of the 2A starter.

It came out of a 49 CJ3, or so I was told. I want to put it in my 48 CJ2a.
That is about all I know about it.
