Manual Brake Rod for 74 Duster

Correct me if I'm wrong cause I am not very knowledgeable regarding this. But I thought there was only 2 lengths. A body and b body. Unless you buy and adjustable one but that's aftermarket. I thought the connection was changed somehow on the 73 and up a bodies. Again I could be mistaken about all this.

We r putting on a 1.03 master cylinder on the 74 duster from a dodge Aspen using dr. Diffs. 4 to 2 bolt adapter plate.
