49 Chevy vs 49 GMC

[Tuned55]

I looked at a 49 GMC for sale last week and told the guy I'd buy it. He then told me he'd deliver it. I got a phone call yesterday from his buddy and siad he was heading my way with the truck but the hood had blown off and is noow missing. The truck is a pretty complete builder but I was after the sheet metal more than anything. Body and floor is pretty solid. My question is pow difficult is it to find a GMC hood vs a Chevy, cost difference and availability. Could I used the fenders and change hood and grille to Chevy if all esle fails. I'd still like to buy the truck if he will adjust the price.
Thanks
