My (presumably original) 044ti in my 250tis are beginning to sound a bit hissy and edgy. A few years ago, I bought a beautiful pair of threaded 044ti off the web before I knew there was a difference. I'd like to try the threaded pair but face the issue of how best to adapt these to the 250ti. I am leaning towards using smaller diameter wood screws versus drilling out the threads on the replacement 044ti. I wonder what others have done here? If you have used smaller diameter wood screws, did you drill new holes? Is there enough clearance in there to get access with a cordless drill?
