4 way flasher question and find

[62 Longbed]

In my 62 I have the Flarestat Flasher Assy. #2234058 Complete as pictured in the 2nd page shown .. With the Red Pull Knob ... Works Great !!!!!
But I also have 2 of the other Flarestat Flasher Assy. that I believe came on 64-66 Chevy and GMC Trucks ... I will post pictures , but its the one that installs thru a hole on the dash usually in the metal on the drivers side ... Great Score !!!!
The Radio Delete Plates should be the same for 60-63 with the ridges ..and I believe the 64-66 are without ridges .. just flat ... They tend to follow the same visual look as our glove box door ...
