I used a Dremel tool to notch the plywood so the crank fit inside snugly and flush to the front. It did not go all the way through. You are right, only 1 of the bolts goes through the crank. There is a large fender washer on both sides of the plywood sandwiching the crank and the other 2 bolts help pinch the washers together and keep them from shifting. They are only 1/4 inch diameter bolts. Has been very strong so far. I had to do it that way since I checked several places and could not find a reverse threaded nut or even one right hand threaded that had the same thread count as the pedals. Friend had old cranks and they are aluminum so they weren't hard to cut.
