Talk with Kim at PKT axles firstname.lastname@example.org He has experience with OTK products and machines ALL of his axles for inboard sprocket carrier. His products have a long standing rep for high quality. He also has a really kool kit to adapt Sniper alignment adjusters to OTK chassis’s.
Full disclosure, I am a PKT Dealer in Nor Cal , but have used his products personally and professionally since 2008.
Best of luck!
