frankenstein 13brew motor questions

hey all, just had a few questions regarding my FD's new motor setup:

- 13b w/ 8.5:1 FC rotors, FC front counterweight and a RX8 e-shaft. I am using the smaller (FC sized) thrust washers/bearings etc to match up with the counterweight.

Question #1:
I am using an e-shaft bolt from a RX8, is this ok? Or should I be using a FD bolt? Thread pitch is the same, both have a groove for an o-ring but the RX8 bolt seems longer.

Is it acceptable to use the RX8 bolt with a FD front main pulley? Or will I need to switch over to a RX8 pulley?

I believe it should be ok to use the RX8 bolt w/ the FD pulley, FC counterweight & washers/bearings but just wanted to double check. Endplay with this assembly seems good (.0020in).

Thanks in advance!
