Further to Howard's suggestion and with many thanks to the Flackmaster for coming up with the control knob, and all those who inputted, here are a couple of photos of the wiper motor and the 'exact '39-appropriate knob', showing the knob lever connecting with the motor linkage. Much to my surprise, once turned on, the wipers worked perfectly!!! Many thanks again for the help!

When I got my '39 Six, the steering was unusable. The open-face thrust bearings that stabilize the sector wheel in the steering box had disintegrated and there was at least a half a steering wheel revolution of play. I had to remove the steering box and had a local machinist make some bushings as the open face ball bearings are no longer available. This improved the steering, but there is still about 6" of play at the wheel. I have been told it is important to line up the 'high spot' of the steering shaft worm gear with the center position of the steering wheel or there will be excessive play no matter how exact the steering box bearing tolerances are. My question is: How do 'find' the 'high spot'??? I can't see any markings on the worm gear. Does anyone know the correct procedure to line up the sector wheel? When I put it back in, I tried to have the wheels straight and have the worm gear engaging the sector wheel as close to the half way mark as I could, but in rethinking this, it would be so easy to have the worm gear off by a quarter turn or so, either way and 'miss' the 'high spot'. I talked to a steering box rebuilder and he said even if a rebuilt steering box is reinstalled with the worm gear misaligned, there will be play. Any advice or help here would be hugely appreciated.

I most definitely will Howard - glad to.

Thanks David - I will 'go email' from here...

Thank you Fred & John. If nothing else, I am appeased that I have not been inhaling asbestos particles. I will probably wear a cup filter mask in the future anyway just to be safe, but I am glad I don't have an asbestos remediation task on my hands!! Appreciate your input.

a little clearer, maybe??

Here's 'where it is and what it looks like'........

Don, yes '39 is a vacuum wiper motor. Somebody posted a picture of their car with a seagull sitting on the hood; the wiper switch showed perfectly in it. I'll try and find and post.

Thank you David, and no, I didn't think you were ignoring me, just figured you were busy - no problem.

I tried to isolate just one page of the following link to show just the control knobs,with no luck, but if you scroll down to where they are shown, there are a variety in the '39 range. Does anyone have any experience with Bob Drake Reproductions?? And/or does anyone know if any of these will work in a '39 Six?? I am presuming the wiper motor in the Packard was used in numerous other vehicles and makes of the time.
