Thanks for the clarification Ross. Your description and direction makes much more sense than my original interpretation. I'm hoping to get out for a test run in the next week or so and with some luck will find the OD unit is operable (and the driver is still capable of learning something new).

OK, I think I understand the steps I need to take to initialize OD, use while in motion and disengage OD. As my car currently has the lockout knob pulled out (OD disengaged) I should do the following:

1) Start and drive normally until above the lower limit OD speed.

2) Once at or above the lower limit OD speed push the lockout knob forward to engage OD (green signal light should come on on the speedometer)

3) To engage OD while driving above the lower OD speed limit, momentarily release pressure on the accelerator and OD will engage when accelerator pressure is resumed

4) To temporarily disengage OD while driving, press accelerator to the floor to cut off power to the solenoid and depress clutch to reduce torque.

5) To fully disengage OD pull the lockout knob out while driving below 60 mph.

Last remaining questions are can I leave the lockout knob pushed in (OD engaged) when I park my car and if I do that will OD automatically be available for use on the next drive after I get above the lower OD speed limit? I assume there is no harm in leaving the OD engaged while doing stop and go city driving.

Thank you Howard - much appreciated. I have the stock R9 unit. The instructions about controlling the on and off state of overdrive while driving is clear. However, just so I am clear about moving the lockout knob in or out, it looks like any movement of that knob should only be done while the car is in motion and above the noted engagement speed of overdrive. Is that correct?

I bought a 1947 Custom Super Clipper late last year and only managed a few short low speed trips before the winter storage season. Overdrive was disengaged for all of them and has been since I bought it and I'd now like to do some highway driving and exercise the overdrive unit. The instructions for use from the previous owner were confusing and unclear so I am hesitant to just do a trial an error run to figure out how to properly engage, use and disengage overdrive.

I've looked through much of the literature in the archives here but didn't come across any driver/user instructions - mostly service information. Can anyone help with some clear how to's, do's & dont's etc? I recall warnings about engaging or disengaging while in motion and cautions about only using it above a certain speed but I'm not clear about the real rules governing use. Thanks in advance for any insights and assistance.

Looks a lot like mine - 1940 160 Super Eight Club Sedan Model 1803. Some difference so probably a different model. One curiosity question. I'm reassembling mine following a full repaint and see the placement of the outside rear view mirrors on this one are high on the A pillar. Mine were placed about mid way up the pillar and I planned to put them back in the same position. Is there a correct placement for these when they left the factory?

I'm doing some additional clean up following a paint job on my 1940 160 Club Sedan. The old (and original) running board rubber now looks a little shabby against the newly painted body and I'm thinking of ways to freshen it up a bit. While the rubber is still in remarkable shape, there are a few cracked, chipped and missing areas. Has anyone tried applying liquid rubber to fill in gaps or cracks (something like FlexSeal or equivalents). If so, I'd be interested in hearing about what was used and how that worked out. Obviously, I don't want to worsen the appearance or apply something that will not hold up. Just trying to hold off an ultimate rubber replacement project as long as possible. Thanks for any insights.

I've used Intercity twice for long distance transport - CA to PA and NC to PA. Completely satisfied both times. Fully enclosed, modern equipment, load never left unattended, same driver all the way, and very knowledgeable and professional staff and driver teams. Excellent communications and accommodating back office staff.

Thanks all, the trim comes off by prying upwards from front to back. It is indeed simply pressed over a spine running the length of the headlight bucket. Not knowing that initially, it was just really uncomfortable applying a lot of pressure or twist to that thin trim strip. Turned out to be very easy. Here are some after pictures for future reference for anyone looking for the design on these things.

Still tearing down the 1940 160 Super Eight Club Sedan for paint prep. Anyone know how to remove the chrome trim that runs down the spine of the headlight buckets? I thought it would come off like the turn signal trim which slid off wire clips but it doesn't want to move even with some persuasion.

Thanks to all for the inputs - all very helpful. Special thanks to Joe for a fantastic blog and the picture which showed just what I needed. Successfully removed the radiator surround. No need to remove the entire front clip and it was not spot welded in place (at least mine wasn't). Here are some pictures for future use to anyone who may tread down the same path.
