Did solid rivets on the two small center braces PF-137 & 150. Install PF-194 and PF-148 diag. tube that goes from the front of the cabin (firewall to each upper corners of the cabin. That really add strengh to the cabin. Install throttle linkage. Measured and drilled both PF-188 also riveted the two lower corner plates PF-117.
I didn't drilled the lower pulleys because I'm not sure where to drill exactly. The plan is not clear, and on Don's log and Marin's log they didn't install them the sare way so I'm gonna call Buscaddy this week.
