yes it came off of a dodge caravan... the insert well inserts many stips going from side to side are welded on the car.... how do I find this lip? what am I looking for ? I can see the weld around the edge where he welded the stips of sheet metal on but they are big ugly messy welds so it might be hard to determine much... also I saw a picture using the dodge caravan roof turned around with the ridges at the front of the car (ridges of course open) is there a way to cover this with the visor or something? sorry for so may questions this is my first hot rod. I am learing as I go, I just need some guidence

thanks,
simon
