replacing fiberglass hood with steel original

The push-on nuts can be found at most local auto stores in various sizes. I`m not sure what size you`d need, I`d guess 5/8". If somebody knows the size please chime in here. Are you putting the car back to original and therefore need to have the original style bolts for the hood to hinges connection? If not just buy 4, 5/16 x 1 hex head bolts with flat washers. HTH.
