Slight change of plan. The radio that I just repaired was working fine.
Unfortunately Tommy two tooth the truck driver, had hacked into my dash with an after market radio many years ago.
When I went to fit the repaired radio, I realized that the dash would have a hole in the dash that wouldn't be covered by the Mopar 830 radio when installed.
So I moved to plan B, which was to take the Mopar 820 radio that I had purchased,, recap and clean and test it, then fit that into my 53 Truck.
Here's the radio installed in my truck, the speaker is in the center of the dash, here I purchased a new 4 ohm speaker and fitted the new speaker under the Top speaker grill.
I now have a working radio in the truck and it sounds great, it's actually pretty loud at full volume.
