converter

I am looking for an fm converter for my 1939 ford am radio

There is no realistic way to convert an AM radio to FM. First, the existing AM radio filters out the higher FM frequencies. That could be modified by an vacuum tube analog circuit expert, of which there are few if any still living. Second: AM radios carry the audio frequency as changing the amplitude of a much higher carrier frequency; for FM radios, the audio frequency modulates or changes the base carrier frequency. There is no way the existing radio could be adapted to demodulate FM signal.

You will need to consider other alternatives to listen to FM. Like a modern car radio mounted under the dash or in the glove compartment. And even that is a challenge if you are still using stock 6 volt, positive ground.

Back in the 50's there was in fact an FM receiver available that was plugged in line with the antenna that allowed using the AM radio to listen to FM.

Yep, I had one of those. IIRC, you tuned the AM radio to an unused frequency in the 1450 range. As I remember it, it didn't work too well; I could get one station, and that one carried all religious programs. Not much help for a 20's something guy trying to promote a little romance on a Saturday night.

I had many FM converters that would play thru an AM radio in the mid to late '70's. Then I got an FM booster when I finally got a car with an FM radio...... Mark

The problem with the old FM converters is the fact that most if not all work on 12 volts. it is not just an inline thing in the antenna cable. I also have never seen a 6 volt FM converter, but they probably do exist, as volkswagon used a 6 volt system up into the late 60's or early '70's. I was going to buy one off of the parts for sale section of the late V8 forum, but the item had directions with it stating that it was 12volt only. I wanted to put it in my '51 Merc. which is still a 6 volt system. I also was interested in the old reverb units they used to make for cars back in the '60's but haven't seen any lately .
