Can anyone confirm if the wiper motor was gold dichromate. I am not sure if the remnants are gold dichromate or something else.

Thanks

Does anyone know where I can get these grommets. I have checked around but have not been able to source anything. I know that AMK makes lots of styles and sizes  of grommets, but not sure what size these grommets are.

Thanks

wiper motor painted black based on all I've seen.

For the rubber inserts, did you look at the Osborn manual yet?  Do you have it?  I can take a look tomorrow when I'm in the shop

I will check the Osbourne Manual tonight. My wiper motor had no paint on it at all and seemed to have remnants of Gold DICHROMATE, but it could have just been bare metal

Not sure if your asking about zinc dichromate for the motor housing or removable cover?   The transmission housing is just bare cast 
Housing halves may have been plated under the final black paint job before they were assembled so hardware was not painted.  May have been painted in black lacquer and didn't hold up will in many climates

I've seen the removable transmission covers plated in zinc dichromate on other years. Not sure if I have one in nice fresh condition in my pictures but will look

Very interesting. Thanks Jeff. I was referring to both as there is no evidence of any paint residue on the motor casing. You can clearly see some residue of some form of zinc plating on the cover. Looks like dichromate, but could also just be age.

I think that the links are broken as they don't open, but I will go top these threads and have a look

I have see several motors that I thought were bare steel. I guess they could have had a light zinc dichromate coating that did no told up. They were defiantly not painted black because of the date stamps are intact.

Yes it looked that way to me as well. Perhaps a case of different plants doing different things at different times. Also no evidence of the M97 stamp

Checked my pictures and found about a dozen examples ( all 68 San Jose around the same period as yours) all painted black. One example (think its the lacquer as mentioned earlier) where 90% of the paint was missing. Just reporting back:)

Mine must be one of the exceptions as Marty pointed out as the stamps went right on the bare metal. In this photo it does look like dichromate residue

Don't have any good photos but both of my cars have black motors with p/n ink stamped on the end like the one Jeff shows.

For mounting hardware, I found these pictures.

In the first picture, third item down from the top, is the rubber grommet.  The fourth item down is a tubular sleeve, flanged on one end, that prevents the rubber from being crushed.

Second picture is a close up of the grommet.

Third picture is when installed. You can see one side of the grommet.

Hopefully this helps.

After looking at the Ford fastener catalog (1969) it looks like it is a type 3 grommet. But the only one listed is part 353630.  You can check those dimensions against your bracket and bolt.

But I still suggest that you look at the assembly manual.  Another source (that I did not check) is Jim's fastener spreadsheet.  I would think that the bolt is covered, not sure about the grommet.

Great thanks. Did you reuse your your grommets or replace them?
