I put things back together using a regular incandescent bulb in the turn signal spot.  And it worked as it should.  So somewhere in my hypothesis there was a grain of truth.  The power has to go through the flasher to work.  Since a diode will only pass current in one direction unless there is a different LED bulb out there somewhere it won't work.  So heads up to anyone trying the same upgrade forget about the turn signal bulb.  This applies only to those cars like my 63 that have a single light on the dash to indicate both left and right.  Taking it out this afternoon to check the speedo cable.

Yes, a 63.  There are two contacts on the plastic bayonet type sockets, one for the center terminal and the second for the metal case.  I seem to remember that one of the sockets got damaged when I was doing the swap.  Might have been this one.  I had a spare panel I robbed one from.  But all of the sockets are the same except two which have different bulbs.  The parts manual shows the same # for all of them.  And there is no ground that I can see.  However if I apply power directly to the ribbon feeding the bulb it does not light, all of the others will.  I tried it with the LED and the incandescent bulb.  Wondering If somehow the opposite side gets grounded through the flasher.  If that's the case the LED wouldn't work because the LED will only pass current in one direction.  When I put it back in the car I'll try it with the regular bulb.  Thanks for everyone's input.

Note to Jeff,  I'm finally installing the speedo cable i got from you.

Paul,

It occurs to me that one of the socket adapters that the bulb goes into
might have a wider negative terminal

that would contact both of the negative contacts on the circuit board
when it was inserted.  I haven't seen

such, but somehow the grounds (both of them) must get to the bulb.  
Maybe an inspection of those adapters

would find one with a wider negative contact.  Good luck!
