I'm looking to purchase hanging brackets, a speaker, a metal speaker grill, and a radio face plate for my 1950 F-1 radio. I have a AM radio that has a scuffed up face.

 

Crutchfield sell these overlays for their radios for the retro look. Would this help?

As for everything else you mention, I don't know. I couldn't find anything on Crutchfields site. Parts Express might have something.

Would something like a marine application or outdoor speaker system possibly give you the look you want? Crutchfield does sell aftermarket radios that might fit your dash, but they are expensive. Also, is your truck a 6 volt system or 12 volt. If you're 6 volt, that would limit your options.

 

Thank you for the thought; but I am looking for original equipment stuff.
