Here's what happens......... If your old dash is warped bad you'll have to shave it alot and in doing so you will end up shaving alot at the top and it will not have anything left to hold it making it look almost worse. When warped bad the glove box door jambs too. Personally I think the cap is a waste of money unless your dash has hairline cracks only. Having the dash re done gives the truck a NEW feeling. Rick........ whats funny is I haven't even used any of my NOS dashes and do not want to touch them! LOL
