I think 18M might be essentially related to the D84 code, just a redundant way of saying you have 2 tone paint scheme? I would have expected an 18U there but basically I think it still means the same thing, your paint should be Medium Gray Metallic on top and Silver Metallic on bottom.

The RPO codes used to be a sticky here and were compiled and updated by member Bogus. Send him a PM and I'm sure he will be able to send you a copy.

According to https://www.gmheritagecenter.com/doc...t-Corvette.pdf on page 51 it is Med Gray (Met) accent color.

Any 2 digit XXM is a MID BODY COLOR and the paint code is displayed at the bottom of the SPID label. In the case of the early 2-tones you'll notice that both the U (upper body) and the L (lower body) are a "match" and the actual accent color follows with an M prefix.
This car the L & U match at 7781 and the M 7719
The WA for the code 13 on the car is the WA7781 and the 18M is a WA7719
