Thanks John, Alan and Ron! That is really helpful. I am planning on doing the butt weld, I have limited experience but I have welded some sheet metal so I think I will be ok there. Why the 1/2 inch lip? Wouldn't it be easier to weld on the rim/edge? or are you doing this to make sure the door fits flush?
Mine is a fleetside and it did not come with mouldings. I am not planning on putting any on simply because they are fairly expensive and I need money elsewhere on the truck
