Differences between 70/71 and 72 Darts

Yes they will

The hoods are generally the same and interchange, but the adjusting system at the hood hinges is different - you can use a 72 hood on a 70-1 car and visa versa, but you have to use the hood hinges for the hood you are using - 70-1 hinges on 70-1 hoods and 72 hinges on 72 hoods.
BTW, the question was asked back in 2020 and the member hasn't been online since 21.
