Not sure about the 1972 Chrysler location, but up until 1971 the flasher is located under the dash, near the steering column. Look for a round metal can, as described above. Note that there are two flashers, one for the emergency flasher and one for the rgular turn signals. As far as I remember one is located somewhere on the driver's side of the steering column and the other is located at the passengers side of the steering column, I just don't know which is where.
Turn on the emergency flasher and listen or a clicking noise to find the respective item under the dash (I assume that the emergency flasher will still work while only your regular turn signals don't work anymore).

No such thing as a stupid question. Well... most of the time... LOL.
Rather than answer it, here's a link to finding the answer yourself. Download a service manual for your car here: MyMopar - Mopar Forums & Information - MyMopar Tools/Reference
I'll even tell you that it's on page 8-102.
Thanks for the answers guys. I'll look in all those places on the weekend. Thanks also for the link to the manual. According to that it would seem to be located close to the steering column. I had looked around there but couldn't find it. I hope it's not necessary to dismantle half the dash to get at it!! 
. I've spent more time lying under the dash than actually driving it. (That's not a joke btw
The turn signals do work, but they're quite slow and get even slower when the lights are on. I wanted to check the voltage arriving at the flasher or just exchange the unit and see if that helps.

Xlratr, that is where I would start, too.
When checking the system keep in mind that these flashers work faster as more current flows through them (because of a higher load) and slow down as less current flows though them. Hence a burnt out turn signal bulb may result in a decreased flasher frequency, unlike European turn signal relais'. The same goes for a bad ground of the lamp housing or bulb socket corrosion.
But it might just as well be that your flasher is tired.

Thats good information, thanks. I didn't know if the fluctuation in flasher frequency was a fault or not. I'm wondering if it's possible to put a more modern component in there that always pulses at the same speed regardless of voltage changes. First I need to find it though!

Yes, there's electronic units you can plug in instead of the thermal flasher, like the Triscan 1000HD12, among others.
Thanks very much! I was also looking at this unit which allows an adjustment of the cycle speed.

Sounds interesting! However, despite claiming not to be affected by varying loads, the specifications on the housing state "two bulbs".
Other specifications given also do not indicate if it can actually handle the load of three bulbs flashing simultaneously (one in front, two in rear).

Finally got around to looking for the flasher today and thanks to all your input I found it after a few minutes, tucked up under the dash on the left side of the steering column. Not what you'd call "visible" but I suppose that's ok if you only have to change it every 50 years!
And thanks to the electronic flasher recommendation from @ceebuddy she now flashes nice and steady, regardless of engine speed or lights on or off.
