I assume the 74 seal is the same as the 73. There is supposed to be 2 different styles for 73 but I've only seen 1 and it's not repopped. Here is a picture of my original weatherstripping next to a Soft seal early 72 style part. Not even close.
I ended up buying the later 73 style this year at the Nat's. It is not correct either but it is hollow like the original one. Once installed I think it will look closer to correct.
