Terry, the 70 used three wood screws, I think 10x1 but might be 8x1. There is one screw in the top and one on each side, none in the bottom. The front side of the front panel has a counter bore at each of these screws holes with a Tinnerman speed nut to support the speaker. The screws pass through the speed nuts and screw into the front arch.
