The speaker needs to be the 10ohm style, or you will damage the radio unit.

Agreed, I spoke with the guy there about the speaker for my 68 burb. He was very friendly, and full of information to share.
I ordered a speaker from him, and it was at my mailbox a couple days later.
Very pleased with doing business with this outfit, and the product is exactly what is advertised.
