Topic: 1969 side marker gaskets

[orlandod]

Doing a few touch ups on the Mach 1 and I ordered side marker gaskets and a pack of speed nuts that came with some soft black rubber washers. I need to know the sequence or order they go in.

From the outside
1 Metal bezel
2 Foam gasket
3 Car body
4 Speed nut

Does this soft rubber washer go between the body and the speed nut?

Or does it go on the studs first?

Yes the stamped self threading nut is supposed to be filled with the mastic sealer on the front valence markers while an empty nut is used on the rears because they were protected from water by being in the trunk.
Anything to save a milli-penny by Ford instead of using all the same nuts.

The question was about the rear side markers. The nut there is Ford p/n 374566-S100, 5/32 self threading stamped, and was specified by Ford to have a sealer. (Note: AMK supplies the nut without a sealer as p/n 374566-S36, and also sells sealers separate, see AMK B-11445, 2014 cat pg 167). The tail light uses Ford p/n 45274-S36, 1/4-20 machine thread stamped without sealer. I don't think they are interchangeable. 
The front side marker is Ford p/n 376762-S2 1/4-20 machine w/disc washer w/o sealer. A different style.
Thank you for pointing out these odd Mustang idiosyncrasies. I will endeavor to include the other hardware items I determined to need correction in the next release of the  Mustang Hardware Spreadsheets- see the Library section of this forum.

The side marker bezels are all the same with tapered pins to accept a thread cutting nut, they don't have machine thread studs.
Now that you've spec'd it, I do have a vague recollection of  the sealer being used with the rear marker nuts and not the fronts which seemed backwards to me since the front marker is subject to so much road splash.

Have you got a reference for this, plus part numbers?

I I recall correctly the rubber inserts should be in the nuts when the worker grabbed them out of the bin and put them in their holders located/wrapped around their waist

Metal bezel then - lamp housing then-  gasket were sandwiched together and inserted into the hole from the exterior of the quarter panels and the nuts were treaded on each stud from the inside/backside

Pictures from the unrestored picture thread section of the site showing the rear mounted ones





Notice that for some reason the upper taillight nuts on the top example have sealant (which serves no real purpose that I can see)- yes I realize that its off topic but don't expect the discussion to take off. And if it does we'll split it



If your focusing on the front marker light then you will also have a wire retainer you will need to consider also that is held in place by the forward nut on both sides. You didn't include where and when your car was built so don't know how much of the details int he picture below apply but the example is a late Dearborn 69. Details often differ if your car was built during a different time period or plant

Did not know about the front retainer. Thanks for pointing that out.
Is this something NPD sells?

The car is a San Jose 3/18/69

I haven't seen it in the AMK Products catalog, only here:

Not cheap, but unless you can find used, it is what it is.

There is only one part number to be found for the bezel being C9AZ-15A440-A for LH/RH/ and fr/rr, just the lenses differ in color front to rear of course.
This also matches my car I bought in '81 with original paint and having never been apart.

This is not in agreement with the 69 Mustang Electrical Manual, it's not the first time what engineering designed was not done on the assembly line. What is shown in the 69 manual for a side marker lamp assembly and its installation is closer to what was used in 1968.
Ford Car Parts (aka MPC) shows a similar front side marker lamp as the rear, just about what you described. I will update the 69-70 Mustang Hardware Spreadsheet to reflect the MPC.
The wiring retainer bracket as shown in the picture in Jeff's post, and as depicted in the Scott Fuller website is not in the MPC illustration (See below) yet it exists, I have three sitting on my desk right now (hint).

Since you mention the car being a San Jose car need to share that I've not yet found one used on a 69 built there. Not sure why but wanted to report the lack of findings for that plant and year. Also don't have any examples with the zip tie we find on some others in the wheel well built at other plants

With the number and possible wide variety of headlight and front side marker wiring and retainers this might be a good subject for another thread just focusing on those to see what we may be able to figure out

[orlandod]

NPD sells the clip as item #382239-S as do others vendors but at around $20 each not on my shopping list right now. They also state the following...

1968-1968 MUSTANG ON OUTER PARK LIGHT STUD
1969-1969 MUSTANG ON INNER MARKER LIGHT STUD
1968-1969 COUGAR AS REQD

The car is from San Jose in March of 69 with no retainer or zip tie but then the car is not completely original ether.

Great. Someone did their homework (part numbers are your friend). The "clip" has been documented in the 67-68 Mustang Hardware Spreadsheets for 68 Mustang use, and has been added as used on 69 Mustangs in the 69-70 Mustang Hardware Spreadsheets (see the library). Its use will appear in future spreadsheet editions.
