I just called them and sent an email and had a call back with in twenty minutes. Very nice fellow to talk with and I will be sending my 67' AM radio this winter for a conversion. As it stands my AM has never worked, so it's not a bad investment at this point. He sounds top notch to me. There are a few levels to choose from starting at 435.00 up to 635.00 I think. The plug in ports are in the rear too, so it should still retain stock appearance out front.
