I am ready to rivet my rear belt line (floor is in and bolted). Everything is in place. But I am hesitant because of the space that is greater than 1/8inch between the skin/hold down plate and the c-channel. The skin is approximated properly on both sides and clecoed in place. My concern is that if I do not get a good approximation at the plate, it will cause weak joining and lead to shearing down the road. I am also using Olympics ( I know, I know it should be bucked).
My current thought is that I should loosen/remove all c-channel bolts to allow it to move and close the gap better. I also have a strip of aluminum from Home Depot that I could place in the space to prevent gapping in case I decide to go that route. But I am leaning towards the first option. I was hoping to get some comments to help me decide which way to proceed.
I haven't seen it mentioned, but it makes me wonder if the plywood shouldn't be notched to accept the hold down plate.
