Looked for the Tip-up Stiffener installation instructions - no joy. Stuck on rivet call-outs. Think that MSP42 would be correct, but need to confirm. Will have to contact Vans ... and get new instructions.
In the meantime, finished a few tasks; 1) trimmed the side panels for butt-joint, 2) added a few rivet locations for end of side skins, and 3) checked all holes for C/S and prep to rivet.
Some additional edge deburring, and assembly sequence review.
