I justt read a post that included pictures of a 1976 FJ40, which had an AM/FM radio in the dash. I thought that AM/FM radios only became available in 1979 and later? Does anyone for sure when they were available? I am restoring a 1978, and I have both AM as well as AM/FM radios that I can install. i thought to be period correct I needed to use the AM only radio. Any insight in to this? Thanks, JMP
