    I thought I would post this thread and add to the database images of the set with the LED mod in progress.
    So far I have the lamps exposed and waiting on the Mouser order.

    One other thing: The entire dial, back lighting harness is missing. wire, sockets and lamps all gone. A guy horsed in two fuse type lamps and hot glued the lamps on either side of the light diffuser.

    If this thread rings a bell please post your images or thoughts.

    The original dial defuse'r lamp holders are missing so I had seen Marks replacement holder and will use that with a set of wedge LED's from eBay.

    I received the LED's ordered from Dave.
    The "White, 4mm wire lead diffused LED's with in-line circuitry" for all the selector switching indication. They fit like a glove.
    So far:

    Indicators are done. Took about 1.5 hours to complete (9 total).
    The "Stereo" indicator will light in both polarities but works like it should in one way. I used jumpers and tested the indicators before connecting the leads permanently.
    Waiting on the Dial lamp sockets. I see their here in town, hopefully tomorrow I can finish this job.

    I finished the mod this morning and it really made the set pop.
    The sockets from Mouser fit perfectly. The only issue is that the pointer string runs close to the socket wiring. I secured the socket harness to the defuser so the two do not become tangled or damaged by the tuning operation.
    The dial lighting is from the "Light Blue" wedge LED's.

    I checked out the settings for Dennis and cleaned it up a bit.
