Since the cab and the fenders on Chev and GMC are the same for those years, I would think the swap should work. However, the GMC hoods are rare and are worth more money than a Chev hood. Depending on your ability, I would question such a transplant. You would have to use filler and between the flexing of the hood while you are driving and slamming it, you could create something ugly. Chev hoods are around.
