Default Bolts etc

I had my IA buddy help me with the install. The bolt bushings were too long and we machined them. The index bushing was way too long and was machined flush with the starter gear. The other 5 bushings were machined down about .050". None of the bushings bottom out, fortunately!
Hub was torqued and tripple checked, safety wire with plastic tubes.

I added prop leading edge tape and we did a dynamic balance again. We spent more time doing it and the final number is .065 ips, not bad. I still have a ground resonance, but that is probably something I can't do anything about...

Whoooooaaaa. How was a flange bushing too long? Those should all be pretty standard.
