If your looking for the original setup where there's 1 knob on both sides of the dial, try this link. absolute classics - Making Yesterday's Cars Sound Great Today .
If you want an updated one , you can cut the opening of the dash to a rectangular opening OR get a marine radio box and mount it under the dash with 2 brackets.
I'm using a Pyle marine am/fm aux/mp3 cd player with a remote head. It's been through a lot of rain before i installed the top on it and it's still going. There's quite a selection of marine radios out there now that i would consider if this thing would just blow up. 4WDHardware and Quadratech has some selection of marine radios. http://www.4wd.com/productdetails.aspx?partID=42092
Thanks for all the help but the radio has been put on hold due to the motor issues. When I do get back to it I think I am going to go with the marine radio. Once again thanks.
