Item fit in place of the original release lever on trans just fine. I converted my stock primary drive to an open primary with a rocker clutch. Needed this lever to fit beneath my oil bag and extend past the clutch hub - it did.
The problem I ran in to was the angle the clutch rod connected with the release lever was cocked in a way it would strain and bent my clutch linkage rod. A little heat and smacks from a dead blow and I had her dialed in. Like I said, great quality but needs a little modification to custom applications.
