I'm not sure if we have anything quite like you describe. Take a look at the three different extensions we carry: the 39-337, 39-357, and 39-422. All three have different spline sizes so you'll need to determine what yours is to choose the best match. As for whether they'd operate with a drill, I can't say. That kind of modification is beyond my purview. They may be your best bet though. |

All of the splines I mentioned go over the teeth. I actually don't know of anything that'd go inside that hole. |
