New mast step on existing plywood backing. I suggest making a new wood backing piece to fit. This will require cutting a larger rebate into the central frame. 

Renegade mast step removed. The original was held onto a piece of plywood by 6 machine screws. (You can see the nuts for 2 on the forward frame.) The ply was hed down by 6 woodscrews. 

Renegade mast step in situ (left is forward), with new one for comparison.
