I think the disk before any drilling , being only 6" is balanced, ,drilling a pilot hole would not change that, drilling the three holes for the yoke would not change that ,,making a circle for the universal joint plate to center the driveshaft would not change that. , drilling the four holes for the universal joint plate, placed evenly between and inside the yoke holes and centered between the yoke holes, of course would not cause an unbalance. so i see it as YES, speedy you are right they are balanced. and testing to 110 is proof. glad to see you have it done waiting for the pictures. jim
