Caleb,
welcome to the Stovebolt. This is an interesting question that you have asked. The Autoradio 510 was made in such a way that the width between the controls and the angle that they were set on was adjustable. For some of the auto installations they were installed upside down compared to the AD truck and a different dial glass was used.
The two parameters mentioned above are usually the main problems with fitting the auto radios in the truck. Buick had a radio that had the correct control separation but the angle was wrong. If you do a search on here you will find a post where a member has a 47 Pontiac "super Deluxe" model fitted in his AD truck. It doesn't look lke an AD radio but it is a very good fit, so I understand.
