USA-740 radio finally arrived

[JimCunn]

Had wrong control knobs, but I was able to find the correct ones.

I'm also thinking about reconfiguring my original radio for 12v negative ground.

Correct knobs have arrived. Look good. Bezels are still I'm the mail.

Bezels still in the mail.

Jim, how difficult was it to convert the original radio to the new one....just curious !

[JimCunn]

I haven't installed it yet, but it doesn't look to be difficult at all. You will need to replace the control knobs and bezels that come with the radio - they look nothing like Thunderbird controls.
I changed my 55 to 12V negative ground about fifty years ago.

The dash panel cutout for my original radio is 0.01 inch larger in the vertical dimension and 1/8 inch larger horizontally (1/16 inch each side) than the USA-740. However, I think the cutout for my original radio may have been done by the Dealer.
