Thank you Alan! All heavy duty mounts that have the word "yellow" molded into the rubber should exhibit this type of coloring. I have heard a few magazine writers that have said it is suppose to have just a yellow inspection mark but this is not what Steve and I found. Below are pictures showing the differences in the so called NOS ones that are currently being accepted for "real", as compared to the assembly line version we used. We did replace the rubber with one from an NOS replacement because they are still the same. I will go through the pictures I have to post an original yellow painted example. These were also dipped in paint. Notice the drip that came off the corner of the one in my Challenger!
