68 Shelby turn & hazzard flasher part # and location

I am having some signal issues with my 68 Shelby GT500 lights all of a sudden. It seems you fix one problem and 2 more occur.

The hazzards are not working at all. The left turn signals are very slow compared the the right. I was going to start by replacing both the turn signal flasher and the hazzard flasher. Does anyone hove the part numbers for each of these? I read that people make frequent mistakes by ordering the wrong part even though it may be similar. I want to get the correct one for each.

I read on this forum the Wagner #323 is the part for the turn signal. Mustangsunlimited has one (Part# SF133) and when i called they said it was made by cougarsunlimited.

The hazzard flasher I cannot find except an electronic variable flasher from Scott Drake.

I identified the turn signal flasher under the dash due to listening for the clinic, but I cannot locate the hazzard flasher. Can anyone assist in finding its location?

Does anyone have any other suggestions in regards to this issue. The fuse for the hazzards looks fine. i was going to replace it with 20 amp, but my 20 amp fuses are longer. Does this matter?

Thank you for the help.
