Since it's LH, I'm assuming that's for the cross slide? I'm guessing the 4900-37 nut you found above was from an eBay listing by BMPartstech, right? If you read farther down, he mentions repairing worn screws...probably worth sending him a note.

Yes, I read that. I have ordered the 4900-37 nut. Schedule to be received January 31, 2024. I will check the fit before asking him for a quote on the lead screw.
