Bumping this thread. Please do check out Brent's post in the vendor section and consider picking up a SCAT 4.375 crank.
If the OP can change from 4.25 to 4.375 then we may only need one more person to make it happen.
Brent - can you clarify the details of the Group Buy? Like E4340, billet/forged, nitrided etc.... Thank you.
