Thanks for all the input.
Up till now there was nobody who told me that this will not work.
So I'm thinking just to go for it.
First by building a mock up to be sure that everything is there and fits.
One challange could be to get the pittman arm solved. A Chevy 3600 has a very long pittman arm.
And I'm not in favor of heating up or welding a pittman arm.
