Batboard

Any ideas on how to install a radio shelf in a 1995 Chevy Caprice? I took a look and couldnt make head or tails of where it could go. Just need something that can hold a Spectra, a Systems 9000 box, and has space for a PAC-RT.

When we did the caprices back when. We used a 17"x48" piece of plywood with a center 2x4 support and some Heavy duty "L" brackets . It rested just behind the back seat and attached the "L"s below where the hinges are. Paint it black and mount the radios. We used to fit 2 X9k'S and a eyewitness camera vault with out any problems. Even to this day some of the boards have made it to the 2003 CVPI'S
