Campagnolo Exa-Drive 8 Speed Freehub

[Martin14]

Hi, it's my first post here and looking for some advice.
I'm looking at options to replace a worn-out Campagnolo Exa-Drive 8 Speed Freehub, does anyone know if a newer Campagnolo freehub will fit straight onto the wheel? (Mavic cxp 30) and then would I need a new 8 speed cassette to fit the freehub or will my existing cassette fit?

Or am I best looking for a secondhand wheel or hub with a Exa-Drive 8 Speed Freehub attached? I've tried to find a new 8 speed Exa-Drive Freehub but struggling.

Apologies if it's in the wrong thread.

Thanks for any help or advice!

What's worn out about it? The bearings are stock industrial ones and relatively easy to replace. Usually it's only the outer bearing that goes (due to water ingress).
