1969 Riviera radio Help

okay so I bought an Am/Fm radio for my 1970 Wildcat, the radio came out of a 69 riviera, and I noticed on the back there's a strange connector, can anyone tell me more about this?

 

it goes to an ol amplifyer. my 68 had one . It was a factory amp.

 

It plugs into what is called a Duplex box and is required to make this radio work. It was the top of the line radio option .

 

My 1970 Buick has a mono AM radio, will it have one as well?

 

No. has to be the "Delco Stereo" Duplex box. Its what makes the radio true stereo.

 

Is there anywhere I can find an amplifier? And will this radio fit in my 70 wildcat?

 

Will this fit?

 

That looks correct but I think its overpriced

 

Hi. I have what you need. I'll get a few pictures tomorrow morning.

 

Could you PM me pictures price and info, thanks
