Title: 66 Driveshaft Markings - C Code Automatic
Post by: rrenz on June 30, 2016, 10:17:29 PM
Curious if anyone has any insight on the factory markings.Replacing the u joints on my 66 C Code NJ coupe and would like to replicate the factory markings. It appears as though there are 5 stripes on my driveshaft. The two in the center appear to be the aqua color and pinkish color. However the three colors at the rear are completely gone.

I suppose that you read this thread. Might provide you with a possible answer to the rear two stripes. There is reference and markings from a very close similar car/example

Often there were identification markings and then additional markings added form other reasons

It's a bit dark here and not much space to look under the car but, I can slightly see what it looks like 3 yellow stripes close the rear axle. When I have the time, I will jack-up a lil the car and see if I can find more info.
Btw, is there a way to clean the driveshaft without removing the yellow marks/numbers.? Just clear water with maybe some soap will work.? Thanks.

I used Evaporust. It took off the rust without harming the paint.

Might check to see if something like Naval Jelly is available and test it in just a small section of the painted area and time the application to a short period then repeat if needed.

Light colors often look like other colors due to exposure, the elements and age. Once down to the paint you will need to lightly sand, steel wool or other wise remove the top oxidized surface to get a better look at the true color

White, pink, tan, and yellow can all look like one another if you skip this step.

Last option would be to use lye on a section of each stripe (it will remove it completely leaving nothing) it will bubble and expand in the bubbles but will let you see the color as it removes. By doing only one smaller section of the larger stripe you will get a chance to try other options. Oven cleaner (over here) is a handy way to purchase it. Spary it carefully in a container (like a glass jar) and apply it with a brush. Watch and take care with eye, hand and skin protection from splatters and spray

Thanks Jeff, will try those options to see if I can recover the true color of stripes.

Sodium hydroxide (lye) is also the principal ingredient in drain cleaner. Nasty stuff, but very effective. Can also be used as a rust remover, and will not erode the base iron or steel. I will add emphasis to Jeff's comments about safety. Make sure you use protective equipment.

Well after allot of research and very small specs of paint under a magnifying glass i found and determined that both ends of the driveshaft saddles were painted with some sort of red paint or primer and the yoke had evidence of yellow paint on the bearing caps. I found one salmon stripe and a fatter aqua stripe in the center.very sloppily applied. There were three more stripes at the axle end of the driveshaft however I have no evidence of what colors they were. this is ultimately what i ended up with after a few afternoons. I can't say for sure if this is the original driveshaft. PO switched out blocks at some point so i have no way of knowing if the shaft or yoke is original to the car however i would assume that it is.

Just for the record - what transmission did your car originally have and when was it estimated to be built?

Here's my marks, well, more or less because apart from the marks, if there's numbers there (guess there are!) i can't read them.
One mark looks greenish and the other white. I can't see any other.
Close to these marks, there's something that looks like numbers, but unreadable for me unfortunately.

Think I can barely read something like 1 9078-, but not the rest.
Have to clean a lil bit more and see if I can read the rest.

That number is NOT a Ford number. It was the stock number of the tube's manufacturer. It appears on some drive shafts because it was stamped about every 6 feet and drive shafts were around 50 1/2 inches. The stamping caused me concerns when I saw it on a drive shaft back in the late 80's as it did not conform to the Ford Motor Company part numbering system.

Hi Jim,

Yes, I assumed these numbers weren't issued by Ford itself, because they are completely different format as the common Ford numbers, and also because I followed the tread and someone did mention that.
