Thanks themechanic, forgot all about that thread. The kenwood's will fit in the kick panels and will clear the parking brake pedal. The only trick it cutting the hole in the right spot of the kick panel so the speakers magnet sits in the recessed area of the jam pillar. Not that hard to do. Like KIWI mentioned, a center dash dual 3.5" speaker set up mounted to the custom braket from '74 Dart will clear a radio, but the heater control cables are a tight squeeze. One thing to mention there is if you have a standard 68-70 dash with a factory tach, the magnet's in the center speakers will pull on the dial for the tach. I had to install a piece 3" x 3" of low magnetic permeability material on the left side of the magnets so the wouldn't mess with the tach.
Right now i'm running two polk 3.5"s in the center, two Kenwood 4" Excelon in the kick panels, two Polk 6" x 9"s in the back tray, a 12" Kenwood Excelon Sub-woofer in a non vented box in the trunk, a Kenwood 1200 Watt 5 channel amp, and a Kenwood Excelon deck with bluetooth, pandora, hands free calling, usb and Ipod hook up. The car is completely lined in rattletrap sound deadening/acoustics and sounds phenomenal inside. Perfect for blasting "Black Betty" or "Mississippi Queen" while laying waste to all the funny winged tupperware contraptions with their press on chrome rims and chainsaw mufflers.
Good luck!
