We supply the rockers to Mancini and they get the shafts from another source. We have run into discrepancies with this before when making these rockers. The simple solution is to run the rockers on a hone to open up the holes slightly until they slide freely on the shafts. The second option would be to grind the shafts to a small OD, however it would likely be more difficult to find somebody who could do that. If either of those 2 don’t work you could send me the shafts and rockers and I can hone them here for you. I’d have to charge you $30 plus the cost of shipping to get this done for you. If that’s what you want to do you can send the parts to the address listed below in this email. Make sure you include a note.
