[Don Turley]

Based on my experience, the way that I would assemble all of this is to start by installing the wood header where it belongs along with the rest of the top wood. Then attach the metal header cover, starting at the center, working both the top and bottom edges together. I would not drive the nails all the way in just yet, leaving the nail heads up a little bit so that you can get under them and remove them if necessary. Work towards each end, alternating ends and pulling the edges into position using clamps. I think that you will find that the "twist" in the metal header will disappear by the time you get to the ends because it is somewhat flexible. Once you are satisfied that the metal header cover fits properly, then drive in the nails the rest of the way. After the car is painted, then the roof material is installed, along with the drip moldings and roof moldings. The upholstered visor should be installed last, after you have installed the windshield frame and hinge.
