I would take a 2'x4' plywood,place it vertical on the side of the rudderpost holding it with clamps, get the line of the shape of the rudder based on your rudder post.At the top THE RUDDER AND THE RUDERPOST is 10",REMEMBER THAT. If the rudderpost is 1 1/2 (not sure about that, measure yours) the rudder itself would be : 10 - 1 1/2 + 1/2 = 9" where 1/2 is the one third of the rudderpost, the round side that will go around the rudderpost. The aft side is vertical, the bottom is horizontal so that agle is 90, the fore is angeled and has the curve for the propeler fit, the top one is about 1" higher aft and goes down toward the rudderpost. The ruder posts in our boats are all fabricated individualy so they can't be all the same. Yours might be a little diferent from other boats. Now, the side of rudder that is attached to the rudderpost is not flat, it is rounded to fit the rudderpost about 1/3 of it in, for strengh and so it does'nt drag water as well, this side is at least as thick as the diameter of the rudderpost and get thiner aft.
I don't think anybody can help you with exact measurements because we have sanded and painted them a lot over the years. So...
The rods that hold the ruder are not all horizontal. The top and the botton one are the only ones that go across the rudder horizontal. The second from the top goes from higher fore to lower aft, the third goes from lower fore to higher aft, the forth goes from higher fore to lower aft and the fifth goes from lower fore to higher aft . They create some trapesoids so the 2 or 3 pieces that the rudder is build out of don't move up and down.

Hope you have enough info now. Good luck.

What are you going to build it out of ? Teak or glass ?

Thank you for your prompt rudder specifics and advice.

My intent is to build the replacement from teak.

Best regards,

Emory
