Without going into details, I am in need of knowing the length of the bolt for the hub. Mine is broken off and the other half is gone. Callies (2001 era Stealth crank, 3.875 stroke) drilled the cranks further in to lighten the crank. So, a standard 2 1/4 ish bolt isnt the size in there.
I need to know, before I go to the machine shop or try to drill it anymore (I have been doing this with a left handed 90 degree drill in the engine compartment, and left handed bits, but extractors are able to get that deep or bite even with flutes), what the length of the bolt is. If you know, please help.
Sure, if you want to pull the bolt out and measure it, that would be great
