Thanks HB.

There are Napco's, Factory Napco's and Factory 4WD Chevys and GMC's. Spicer 23 and Rockwell T-221. So these decal sellers have Napco mixed in with GM factory shift patterns. GM decided to use the Rockwell T-221 when they "built their own" 4X4. So Spicer 23 was gone in 1/2T in 1960.

There is also a Black Metal Plate for Napco Powr-Pak.
