66 Hertz leaf springs

[tomhawk]

Has anyone seen orange paint on their leaf springs. Just removed mine yesterday. Found the usual yellow and green stipes. Then on the pair is an orange stripe on the spring and rear clamp. Including a pic hard to see but gives an idea where the orange is. Springs have some rust, but can clearly see orange paint. I have seen orange paint on hipo flywheels and cranks. May indicate springs are for a K code car? Also have noticed on restored early Shelbys looks like the yellow and green paint has been sprayed on. Mine have always been a brushed stripe.

Considering you have what appears to be orange on the banding as well...Im going with not factory, but Im sure you will get some other ideas

Guess you have already looked and confirmed the engineering numbers

The paint ID markings for the same springs would be the same if it were on a Mustang or Shelby. Given the location of the orange paint it appears that it was likely someone with a spray rattle can painting them for some unkown reason. Seen hundreds and orange on a 66 Mustang or Shelby spring is not typical

Of course it is your car and you can do what you want but I am with Jeff in that it believing it is not a factory marking typical or otherwise. I like Jeff have seen many dozens of original unrestored that don't have the orange. Just expect push back if trying to convince others.

I believe its factory. ..............

Just for conversational purposes what do you base that on?  A mistake by a worker at the company that supplied the springs?

As for the green and yellow ID the use of stripes verses spray dots depends on production period from what I found over the decades of documenting these details

Soak them in evaporust.

Watch how long you soak them.. The paint came off my driveshaft from evapo-rust.
