stereo camera focus

I have a '53 vintage Videon stereo camera that is from my wife's family
The shutter would not cycle, the lenses are screwed in from the front, I removed them in the past and replaced them after realizing I was in over my head. Recently after reading of the magic of ronsonol I reremoved the lenses, bathed the shutters in ronsonol and they now cycle. after replacing the lenses they both are not in focus. is there a quick fix for how close they should be to the body a difference in right and left? I reinstalled them as close to the camera body as I could and be able to join them with the rod on top. I know they both need turned out because the entire photo is out of focus in both lenses. I know the ground glass on the film plane plan, but I'm trying to get my ducks in a row before I do anything else. I lost the last screw on reassembly last time, the one that holds the pivot between the lenses, so I'm trying get help before I need it. also if I have it apart again I didn't lubricate the mechanism the last time, what would be appropriate? I could see the oil on the shutter leaves but at 50 years old who knows what conditions it was stored in

Thanks in advance
