I'm looking to install a period correct radio in my '73 E, but can't find a definitive answer as to what radios where available in this year/trim (my CoA also doesn't list one). It seems as though the Blaupunkt Frankfurt and Beckers were standard, but most of the links I was able to find where outdated or dead. I am aware of that I need the US and not RoW bands.

Just want to make sure I get the right one so thanks!
