One type had a center to center screw hole spacing (for the screws that hold the brackets to the keyframe) of under 6” while the other had a spacing of over 6”. Regrettably, there’s no knowing which type you have until you pull the action and measure. Just be sure to reset the action spread and allow for regulation in the cost of the job.<o:p></o:p> <o:p> </o:p> Here’s a little trick that might come in handy, while being mindful that’s it’s only a temporary band-aid while you get parts: remove the acorn nuts on top of the hammer flange rail so you can slip a section of let-off button rail out, place appropriate balance rail punchings on the studs and reinstall. This saves a ton of regulating with turning the let-off buttons down to make it work and then back up when the new brackets are installed.  A caveat to anyone else reading this, it’s not a permanent fix since expanding action brackets will continue to expand.<o:p></o:p> <o:p> </o:p> I hope this helps,<o:p></o:p> <o:p> </o:p> <div> Allan<o:p></o:p> Allan L.
