the Ef johnson Challenger series radios are quite flexible for older technology. You can take a dash mount radio and convert it to remote mount if you have the remote head and junction box.


These are connected to the junction box via a n 8 pin modular connector, that resembles an RJ45, but its just a little smaller. You can easily file down the sides of an RJ45 and make it fit perfectly.
