S&M Decal

First I want to thank those Mopar enthusiasts who make this Forum so great.
I mean, I find most anything I look for. Thank you.
It is possibly though, this will be too hard for you...
Apparently the Sox and Martin team manufactured some racing related parts and sold in their Shop, and possibly also later in the early seventies, through Mopar Direct Connection, as was the case with a adjustable Pinion Snubber, on witch you found this Decal.

So, I am looking for this Decal, background must be in blue though.
