Souped Up Factory 67-72 AM/FM Radio

[kna4977]

I've heard that the original factory radios for the 71-72 trucks had to be fairly close to the radio tower to pick up a decent signal. I've also seen several of these radios restored to like new condition. My question is has anyone considered, or does anyone make or refurbish a radio to look like the original factory AM/FM with today's components that would work a lot better? If so, where could I find one? Basically I'm looking for a radio that looks original on the outside but has today's technology on the inside. XM or SIRIUS capabilities would also be nice.
