Ignition Coil Capacitor Part Number

I was looking at some upclose pictures I had taken at the VerHage Mopar museum and I can see part number 2107674 stamped at the end of a capacitor on a 1968 Barracuda 318 but when I checked the '68, 69, 70 and 71 Mopar parts book part number index, this part number does not exist.

Anyone have any info?

I will try to post the picture of the capacitor.
