Here's the forward tunnel cover assembled. Since it's held in place with screws, I'll just put it in place temporarily for now and then pull it out to prime and paint next spring when the weather warms up.
I came close to getting the seat backs finished. Everything is riveted together except for the angle on the top edge (under the lip) and the top piece of hinge that the seat back brace connects to. I didn't do those with everything else because I need to change my riveting setup to reach the rivets. I used the squeezer on everything else, but I either have to use a gun or the c-frame for the angle and hinge.
