Need help with drill press chuck

[Slednut]

I need a new chuck for my drill press, obviously I want to order the right chuck. Do these tapers come in different sizes or will most 5/8 chucks work on this taper?

Using a tape measure to measure a spindle taper Wrong tool for the job

It is probably a JT33. What does the old chuck say?
