Ya got that right.

Even DaveMade, Midnight Special, and the other amp brands now offer to bias their amps to AB so they don't lose customers to Texas Star.

As you know C class amps were intended to run on FM mode by design; not AM.

IIRC, most of the CB AM only radios run Class B output. Should run a Class B amp; think that Midnight Special amps builds them that way. Most SSB/CB radios are AB Class outputs. Also, an AB Class amp for a CB/AM only radio is an improvement overall. They might run a little hotter and draw more amps than a Class C but should put out just as much power. While offering little in the way of spurs and harmonics. Of course, this is all moot if the radio is running more than 100% modulation . . .
