Probably won't surprise anyone. The finger with the deepest groove is as much taller (0.020") than the other two as the groove is worn deep.
A buddy told me to remove the old bushing by "just" filling the bushing cavity with grease, and then placing a 3/4" brass drift in the filled cavity, and hitting it with a hammer. Bushing didn't budge on the first try, and I'm not very comfortable putting a side load on the main bearings by pounding on the end of the crankshaft with a BFH. Maybe I can get in there with a hacksaw blade, and cold chisel out the cut through parts.
Not sure how to measure the bushing opening in the end of the crankshaft. It doesn't look like my dial caliper tips will reach in there, and I don't think my neighbor's dial indicator has an attachment that goes that small. I may need better equipped neighbors!
