Finding NOS hood or a use Cowl induction hood will be more costly then a reproduction hood. Most 70's used a different hood than 71-72 cars used. The difference is in the underneath structure where the front hood insulation goes. There are late production 70's that used the later style. Earlier versions before late February 1970 were open along some parts of the edges were the hood insulation would go in that you would actually have to use glue to make the insulation stay in place. The later version after February 1970,the edges were closed through out the insulation pocket that you could just slip the insulation right in and the full edges would hold the insulation in place. Your 71 would be the later version. If the bottom structure of the hood is three pieces it is original, if it has just two it is a repro. Most people can not tell the difference.
