Hi PaulI am sending you some photos of the shaft with 427c.i.  engine bushing and i will keep using the original planet housing with some modifications and hold it with 6 of  12 mmx45mm shoulder bolts but the diameter have to be grind of .052" to meet the small gear needles beering i,dia, and .375"dia 6 pins from roller bearing,the shaft will be drilled between the 1st and second bearing bushing at .250"dia straight true for the prop governor oil pressure passage way.The insert cup have a tap hole for a set screw to be plugged when using the oil pressure constant speed and this cup will be pressure fitted.I am very close to start the machining on the housing with all those oil passageway,i did have 2 casting set in case i do have to make some changes at the assembly and then use for the second engine.It takes time and money but i will come to the end of this drive project.
