rear side marker interchangability question
Would anyone happen to know if the rear side markers on a 71-73 Mustang are interchangeable with the front side markers from any other Ford product?

It appears that some of the japanese Mustangs I've come across have yellow rear side markers and some have red and without a part number I'm just trying to see if I can figure out the origin of these markers and the easy answer is that they are the front markers from another application.

mwilson7, tracking things done to export cars can be tough. The passage of 40+ years, non existent DSO records, and the staggering amount of bureaucracy and red tape to make each car compliant for a particular country doesn't make things easy. Some changes were done at the assembly plant, others at the destination country. All of the side markers I've seen were amber in front and red in rear which met US DOT requirements. I had spent a few days in Japan before continuing on to Taiwan and remember the American cars I saw having amber front and red rear side marker lamps. The front markers and outside metal retainers (bezels) were unique to the Mustang. The rear, which have a D1ZZ part number, are held in place with the same retainer as the 71-72 LTD which used the same size lamps at all four corners (unless equipped with front cornering lamps). So it is possible that a front amber lamp from a 71-72 LTD could be made to fit the rear of the Mustang. Without some engineering numbers it would be hard to say what was used. Some of our overseas Brothers could possibly give us some info on their country's marker lamp color requirements and how strictly they are enforced.
It's possible that some of the vehicles may have had some damage and a lamp was replaced with what ever could be found.
Don't know if any of this has helped any, as I said earlier the export models are hard to sort out!


No Officer...I really don't know how fast I was going, my speedometer stopped at 140!

Everything you have said is correct. I have someone checking on the LTD front lamps so I appreciate the tip.

I also have someone checking on an actual car with amber rear lenses but unfortunately they won't have the answer for a few weeks.

On a side note I used to live in Whitinsville from 1996-1999. I used to love cruise nights as some really cool old cars would always come out of the woodwork.

Thanks for the response.

not sure on front interchange. Rears to fronts are not interchangeable. Rears ONLY for the most part the same on most 7173 ford products. ( red rectangle marker light in quarter panel). Ive used rear ones off a 7172 LTD on my Cougars and Mustangs.
It is a slim chance but if the Build Sheet is still in the car it will have any unique part numbers in the Remarks section on the bottom of the sheet that were added on the assembly line. I have a Special Paint car and it had three remarks in the lower section that override any of the options or parts in the top half of the sheet. Mine is so dirty and damaged never been able to make out the numbers. Even sent to Marti hoping he could help but nothing there either except for the second comment. I attached the scan so you can see what I am referring to, you will need to zoom in to read. Something about hood and the second you can read Install Argent Front Bumper.
If your car required a special order from a DSO like this car for paint and other items in the remarks it should have a six digit DSO code. The first two are the DSO and the last four are the Special Order number. Pic attached of door sticker with 6 digit DSO. If I remember correct yous is just and Export DSO not a Special Order. Like stated these records were not kept by Ford or Marti so lost unless by a miracle someone that worked at the DSO kept the records.
I know the Mustangs sold in Germany had to have different color front turn signal lens and maybe something in the rear also.

When a man is in the woods and talks and no women are there is he still wrong??

You're correct in that my car just has a regular export DSO of 91 so nothing special there. I'll be home for christmas in a few weeks and am going to remove the carpet and see if I can find a build sheet which will hopefully answer some questions.

I've talked to both Gary and Wolfgang from the T-5 registry quite a bit and both of them haven't mentioned anything and different colored side markers but I'll ask again just to confirm.

I think I may have found which light it is but I'm waiting for confirmation:


Question for the group though. On a 71-73 Mustang side marker what is the difference between the drivers side and passenger side parts? I'm guessing it must be something in the lense as the housing is exactly the same.
