Riveted the aft sides onto the cylinder baffles. Seemed to take a while to lay out where the holes would go, drill around the odd-shaped sheetmetal, and get the rivets in there. It's not easy to get them in place between the cylinder fins, especially now that the aft sides are on, but it isn't impossible. On the right side baffle, the aft side was bent a little too wide, so I overlapped the flange on the aft plate closest to the crank on the outside of the baffle instead of inside.
Left side showing general rivet spacing.
Left side near the engine mount is pretty tight.
Side you can't see the flange is outside the baffle.
