I need help. Has anyone built this 57 vette? The instructions are useless. It is called a flip top in that the hood can be displayed in an open position. I don't want that, I want it to be a solid body. However, the body consists of a back half or third, a front half or third and 2-pieces, left and right, very thin. I can't figure how to put the body together. Anyone familiar with this?
