Anyone remember setting these up for a 19 or an 18-2?

Is setting the rake for the newer style Prindle rudders the same for the older ones... I was playing with it this weekend and it seems almost impossible to get the leading edge about 1/2" aft of the transom which is a good starting point for the old style per the Prindle Owners Guide And I do have the extend gudgeon.



These are the ones I am referring to
