Re: Part No.help 63 Flasher

Can't help with the GM part no., but here's what you're looking for.

Tung Sol AP 373. Has 3 LAMP embossed on the end.

Chuck, Thanks for the pic.

Chuck, Thanks for the pic.

Edward,

In addition to the flasher info Chuck posted, you can also look for a #143 Signal-Stat flasher. Both the Tung-Sol and Signal-Stat were used for 63's w/o back up lamps. (also used for 61 and 62 Corvette and many passenger cars of the era with a three lamp system)

The #143 is a rectangular unit instead of the round design as shown in Chucks picture.
I'll look for a picture of a real one.

Chuck, I like the rubber on the hood cable. Did you add that?

The original GM part number was GM #3758682, but I don't think you'll find one of those as it was discontinued many years ago. No matter, though, as has been mentioned, it would have been one of the outside-supplied units, Signal Stat143 or Tung-Sol 323.

The last GM part number I can find was GM #461160 but it was discontinued quite some time ago.

You can find these flashers in an auto parts store and they may even be Tung Sol or Signal Stat (but it won't be configured like the originals even if it's the same Tung Sol or Signal Stat part number).

Joe,

In addition to the 3758682, there is also a 3758683. One is for Tung Sol and the other is for Signal Stat. I don't remember which is which though.

I think the 3758683 was a PRODUCTION-only piece. As far as I can tell, the 3758682 was the only one available in SERVICE. GM probably wanted to give the production line options but GMSPO wasn't interested in stocking 2 different part numbers to give parts customers such an option.

I bet that's correct. Both the 3758682 and 3758683 are shown in the 63 AIM but only the 682 is shown in the 63 parts book. I don't remember ever seeing a 3758683 in a GM box. I suppose that those in existance were in the suppliers box.

There are several different varieties of the Tung-Sol flasher. Only one is correct for 63 though.

Bob Jorjorian is our local 50's and early 60's flasher expert. Maybe he'll join in and show a few pictures of the correct Tung Sol flasher for 63. I only remember that the original silver color is correct. The later gold or green colors were later issue.

By the way, none of the flashers used through the 63 model year are correct for any 64 and later cars. They are NOT interchangeable.

Edward,

I believe that I still have a few NOS Tung Sol AP 373V (3 LAMP) flashers in my collection. If you need one send me a PM. I just live up the street in "Tax-a-Hampshire".

Re: Part No.help 63 Flasher

Chuck, I like the rubber on the hood cable. Did you add that?

Yes, I did, Harry. The cable actually rubbed the flasher, so I put the rubber "sleeve" over that part of the cable.

BTW, I had (and still have) a green Signal Stat 143. I was told that any colored Signal Stats were incorrect for 63. IF you could find a natural aluminum colored one, it might "fly" for judging.

I had some pix of Signal Stats and "close ups" of the Tung Sol AP 373, and just can't find any of them now. I know that the Tung Sol's are dated. I think the Signal Stat's are too, but I'm not 100% sure of that.

The 143 flashers fit better and don't forget to get a correct dated one if you plan to be judged. RJ

Re: Part No.help 63 Flasher

The date coding on the Signal Stat flashers is well known but as far as I know the Tung Sol date coding has not been cracked. I have been trying for many years. I have found several original AP 373 V flashers in junk yard 1961-1963 Chevrolets and have owned as many as 2 dozen NOS AP 373 V flashers over the years.

Re: Part No.help 63 Flasher

I read a good post about dating all types of flashers somewhere.
I thought here about a year ago. RJ

Great idea. The outside of the flasher is not suppose to be hot. It becomes hot when the paper tears between the flasher and the socket and contact is made. At that point, if the cable is touching the flasher a direct short happens and things start to burn.

Don't ask me how I know. I'm going to add that rubber tube/hose!!!

Thank You Chuck...........
