Since WorldIRC brought up the whole freehub
compatability question I've got one, may be similiar
I'm not sure.
I bought a campy 8 speed wheelset, problem is
the splines are different than my 8 speed cassettes.
I believe the cassette is exa-drive, the hub isn't.
The splines are different so I can't mix and match.
MY question: Is it possible to rebuild freehub and
put on an exa-drive freehub (whats the term for
the splined part?) piece?

The piece you are referring to is called the cassette body, I believe. I know you can upgrade/swap cassette bodies on shimano hubs, so I don't see why campy hubs should be so different...

I'm sure if you gave them a call they can tell you what you can swap around and what tool you need to do it.
Harriscyclery.com may have them, also, but I don't see them listed at their site.
I went over to Brandfords site and funny thing, it appears
that I might have campy hubs, ShimaNO cassette body, and
campy exa drive cassette. The reason I'm thinking this is
that the spline pattern is completely different. All the campy
stuff shows 1 narrow spline on the cassette body, the body
that I have mounted on the freehub has all same sized splines
on cassette body (I hope I'm clear on this, its confusing enough
I'm gonna give Branford a call.
I spoke with Tim at Branford (Tim Laflin from Campy only?) and
he said 1) try the pre exa cassette, should fit
2) replace the hub, however they don't carrry 8 speed anymore
so his idea is to go with 9 speed and space it for 8.
so I'll give that a try. The different splines? campy provided for
idiot proofing cassettes, can't misalign them this way.

Shimano Hyperglide freehub bodies have pair of splines spaced wider apart than all the rest which accept the one wider lug on the HG cassettes. This is handy because you can't get a cog on backwards. On the other hand with the older Uniglide bodies and their uniform splines you could flip a worn cog over and get more use out of it.

What BRAND are your casettes? I may have solution!
You may have an older Campy 8 speed hub, made before exadrive? I had some older wheels for awhile and and they did work with the newer Campy Exadrive? casettes. I just rotated them around until they slid on. It didn't look like it would work, the splines on mine were a bit different than the newer casettes as well- But It DID Work!!!!!
