It's a pretty simple motor. the issue I had with the one out of my '56 was the cable was solidly corroded and it took a lot of time soaking in Sea Foam to get it to move again. still a little sticky but it works!
May not hurt to pull the motor out and clean up the switch plate and lubricate it tho, the grease on mine was dried out. Pretty easy task if you dont have a radio in there, spring clips hold the push/pull on the motor arm, take out 4 screws, and there ya have it.
