Austin Western Model 55 steering issues

Sorta' new to the forum. I've got a Model 55 Austin Western that I'd like to get back up and running. The thing that I see that may be an issue is the steering box. It looks like it is a "non oem" part, but fairly close. Steering shaft turns but feels like either splines or gear teeth are knocked off. I haven't taken it apart yet and probably won't till after Thanksgiving. Just trying to get a feel for what's out there. Thanks
