Name for Second Color of Two Tone XJ

I searched and did not come up with an answer. I have a black 88 XJ with the lower portion of the door panels, flairs, and plastic trim finished in a silver/grey color (popular option on the mid 80 to mid 90 XJs). I need to touch up a couple of spots underneath the plastic trim, but have not been able to find the name or color code of that particular color. All Jeep customer service was able to do was locate the color codes of PX6 and QX6 based on my VIN, but could not pull up any associated names for those codes. Does anyone know the name of the silver gray color that Jeep used (or a very close match)? I'd post a picture, but I'm not allowed to post attachments for some reason.
