gentlemen here's what i have discovered. i looked up the gm part number i got from the assembly manual it turns out the the 63 switch was a 63 only. well, 63 to early 64, then the part number changes twice for the rest of 64. in my box of electrical stuff i found a switch with the 65 colored wires, and another one that has a completely different set of wire colors. i scraped the insulation to see if the wire colors were surfaced bleached but it is white all the way through. i found numbers on both switches and googled them. one is a 64 the other a 63. if you look at the photos you can see they are different. how exactly they work i don't know. i have located 63 switches that are identified by the 63 part number but i am not sure yet that they are the "real deal" they are pricy.
the "box" i referred to in my post is the dash lights/speedo box. sorry, i should have explained that better. the switch i'm looking for is a 63. part number 8981967. the switch i have in there now is from either classic parts of another of the venders. thanks rolf
