Second, although it is a tension application, the design of the saddles precludes sufficient bolt pre-load to clamp the assembly tight. So, I'm afraid that a poor hole will allow movement of the joint. Basically, the saddles are fit so that when torqued to the rather light pre-load, the ends of the saddle are not supposed to touch the bearing plate. There is supposed to be a gap.

. . . I would consider reaming that hole smooth with an adjustable reamer, to the very minimum amount needed to get a clean hole, and then turning a thin-walled sleeve on a lathe that would be a light drive fit into the hole and provide normal close clearance hole for the bolt.
