OK Chris, I'm confused here.
I was told this:
"Daniel Daniel Daniel, it is not OK to use pop rivets to attach the shell to the C channel. They don't havr the shear strength that solid rivets have plus they have a hole in the middle from the mandrel. You might as well drill the shell full of holes and use duct tape to attach the shell.
On another thread I read:
"The banana wraps and the side wraps of the belly pan are pop riveted to the shell underneath the lower beltline trim."
So the shell is riveted to the C channel with buck rivets, then the shell is riveted to the side wraps with pop rivets?
