It should work nicely with minimal differences I would think.I have the paper that shows the original rudder superimposed over the new design. Have a look and see what you make of it. The leading edge has been reduced and the aft edge extended. Extended overall length, and the tip has been given a more forward sweep. I didn't weigh either rudder, but this one weighs a fraction of the old one. Either way, its the rudder I have so it will have to work View attachment 43133
You are lacking a portion forward of the rudder post on the originals at the top that helped reduce turning efforts on the helm.
My guess is the differences will be minimal.
…Anxious to hear your results!
