Yes it is the original wire. If you look carefully you can see the Ford #s at the top.

FYI NPD has the correct wire cover material part #9278-1K

Great thanks. I am going to need a new wire as well. Everything else looks good and can be restored. I did a search on the NPD website for that part number and I could not find the wire sheath

NPD 9278-1K is now $4.60, as of 10:56AM PDT, 4/24/20.

A picture is worth a thousand words so to show the two sizes of cloth loom I found and their differences in sizing, attached is an image of the 1/8" i.d. asphalt loom I found on the license lamp wire and the 3/16" i.d. asphalt loom I found on my door handle linkages.
Also pictured is a sampling of the new loom I purchased for both of these usages and the respective part numbers for ease if anyone needs to order.
Sold by the foot (currently each at 60 cents/ft.) at Restoration Specialties out of Windber Pa.

I dichromate my license plate housing brake, and would like to confirm of the centre section that is riveted in should be zinc or dichromate. Also curious where to get rivets to place the ones I would removed if the centre section needs to be zinc plated

Only the rivet was zinc originally.

I found mine there. You need to measure the ones you remove and then do some surfin' in their catalog. You will also need a special rivet tool, or at least the two dies to install if you have a press.

It may be easier to mask off before dipping in the chromate. It will wipe off with various chemicals but you will have to mask area surrounding or risk damaging finish there.

I will see if I can remove the dichromate from the rivets

I'm about to restore the license light as well.

The previous owner has made some "nice" modifications, especially on the wire. See pic.

Before I gonne re-chromate the housing, how to remove

- the rubber near the bulb and
- the rubber to the car body

I would like to avoid destroying both rubbers.

What is the lenght of the wire from housing to the car body rubber and the total?

Unfortunately the wiring and rubbers can not be bought in GER.

Looking also to the correct wire loom (https://www.restorationspecialties.com/Wire-Loom_c_326.html) But there are so many different ones....

Thx

If you plate this thing as one piece the dichromate is easily removed from the rivet with a light brushing of a Dremel with a wire brush. Otherwise you need take it apart and reassemble using the proper Rivet Squeezer tool, mandrels and rivets. That's an easy $250 right there if you do it.

The grommet that goes into the body may be hard as a rock. Look up "Wintergreen oil to soften rubber".

To remove the rubber part around the housing use a 4" long (approx) small flat blade screwdriver and move it under the rubber. There are one or two dots of adhesive that hold it in place.

To remove the wire, cut off the button that contacts the light bulb and the whole affair comes apart. When I put mine back I recreated the button with the metal portion of a squeeze style ring connector. Or buy a button from Rhode Island Wire. It's also possible to reuse the existing button if you can pry it apart. Very fiddly.

To fix your wire situation you need to source a similar looking wire and end from an old harness.

There is a sleeve missing from your assembly too. NPD carries the sleeve.

All things considered you might consider to have yours done by someone who has the parts. It may well be cheaper. PM me for a name.

[Ralf]

Thanks Bill.
Sounds not as easy as I thought. But I decided not going to re-rivet.

A pic of what I have.

What do you mean with "sleeve" is missing?
