Thanks in advance.

 

Friend has my old XT8 and notices sloppy focuser movements, recall many replace it.

 

Just curious if the newer improved focuses match same screw spacings??

It depends on the model of the XT-8.  Some had 2 inch focusers and the scopes were manufactured by GSO so a GSO focuser will likely fit. 

 

If it has a rack and pinion, it's possible/likely Orion single speed Crayford may fit.  These are often available used.

If it is a rack and pinion, it can likely be improved by disassembling it and adjusting it...
