I may be wrong, but I think the galvanic difference would accelerate corrosion of the cast iron...May not be enough to matter considering the normal life span of either part..
Yea what Lou said, at least get the drive off and pull the bearing. Buy new parts over winter and put it back together in the spring. And Danforth..he snuck in..
I had water dripping out of the lower shift cable at the shift plate. Water was getting past the o ring in the drive and forced into the cable when running..
You need to understand that water is heavier than oil. You have pumped a mix of water and oil to every bearing in the engine. And as it sits the water settles and displaces any oil on the surface of the bearing surface and then the rust begins..
Well I think you have come to a decision making time for your project. You must realize that every bearing surface is pitted from rust and you need some new parts..
I hear ya, I probably would get some cheap masonite peg board and rough cut it then pull it down to the frames using the holes, to conform it to fit with small screws and make a template unless you can source a piece of cardboard..
