Yes, the game was made in 1968 - all manufactures were still using the 2" flipper.
The flippers mechs would be the same - what the ops did was move the mechs out and replace with a 3" shaft and flipper. If by chance you do get to see this game again have a look under the playfield, you will be able to see where the mechs originally were. Also the original screw holes will be able to be seen.
