The spindle nose type/dimensions will determine which chuck you require if you want a ready to fit replacement.
The subject has been a topic before but nobody could identify which Class/Type/DIN the spindle nose was.
Alternative is to accurately fit to spindle nose and then machine a backplate in situ on the lathe to suit the recess at the back of your new chuck.
If fitting a larger than standard chuck give due consideration to the max rpm for the chuck and additional load on the spindle bearings.
