It sounds like your antenna isn't grounded properly. Check the antenna base
for rust and make sure it's seated directly to the sheet metal of the
fender.

Turns out it was because I didn't have the power antenna leads
connected. I thought power antenna referred to raising the
antenna when the radio is powered on, but this wouldn't apply to
this car since the antenna is in the rear window. Once this was
connected, my AM radio was back.
