5% worked great, thank you. You just saved me a tonne of time trying to figure it out for myself.
As with Braveheart93 above me, I'm a bit confused with the codpiece. I'm assuming the cod piece centre plate is the part that descends vertically and the cod piece left, right and centre is the part that folds off at an angle, which leaves a gap to be filled. Do I line that with bondo? I have experience using car filler to remove imperfections and strengthen things but I've never used it as a bridge between two points before.
