51 or 52 AM Radio (buick)

Does any one know if the 51 or 52 am radio will interchange with anything else? My radio needs a transformer. So i need a parts radio. Thanks Jim

 

im pretty sure 51 and 2 are the exact same

 

The radio in my 51 Special didn't work when I purchased it so I sent it to Tayman Electrical in Sarasota. He converted it to an AM/FM without changing the appearance. It's looks great and sounds awesome. Go to taymanelectrical.com if interested.
