Internally most of the good AM car radios I've met had mechanically
ganged slug tuning, although variable capacitor tuning existed too.

That's great if you're comfortable adjusting the mechanics of the
radio internally to get the tracking right. Remember, you won't be
broadening the tuning range, you'll be shifting the tuning range.

Í guess by about 1990 (20 years ago) they had all abandoned the
slug-tuned stages.

I had a '90 era car radio found in the Caribbean. It locked onto the
9kc European channels. I'm sure there was some chip jumpering that
would allow tuning to American 10kc channels but I never could find the
info.
