I haven't been building much lately, but this truck is back on the bench. To cut the basswood strips, I used a balsa/bass strip cutter from Master Airscrew, adjusted to width, and drawn along the grain of the wood. To cut across the grain, just an xacto with a #11 blade, a steel straight edge, and multiple passes to keep the edges clean.
Jim, not sure if Rob carries bolts like this or not, I've never looked.
