I've looked thru the on line manual and in various parts books, I'm starting to think that the core support is different in the trucks than the pickups despite what the books show this truck has a core mounting in the center rather than two bolts spaced apart the books show 53 to be spaced apart, also the top cross from fender to fender looked to be welded to the supprot at one time but here again the books don't show that piece in the new kit is it welded to the support or just bolted to the fenders.
