Campy 9 speed wheelsets

Hello!
I have a few questions that hopefully the Campy Experts on these
groups can help me out on:

My winter training bike is a mid-90s CroMoly frame Bianchi I upgraded
with Campy triple Racing T and newer Veloce 9 speed shifters. The
cassette/rear hub is the original 8 speed and works OK with the 9
speed shifters, I just have that extra "click". My other bike
(Kestrel Talon) also has Campy triple Racing T and Centaur 9 speed
shifters and I hope to eventually get a pair of Zipp 404 carbon wheels
to race with on this bike.

Ultimately, I would like to have 9-speed cassettes on both wheelsets
so that I could swap wheelsets between bikes. That's where my
question comes in as far as advice on how to do this. The 8 speed
gears on my current wheel has 8 notches to slide the gear onto the
splines on the hub (I think it is called the EXA-Drive system). From
pictures I have seen, it looks like newer 9 speed cassettes have a
different spline pattern than the 8 speed. I can't tell from the
photos whether these 9 speed cassettes would work on my 8 speed hub.
Do I need to replace the 8 speed hub to work with all 9 speed
cassettes? Are there different spline patterns between the different
Campy 9 speed cassettes (e.g., Veloce and Chorus)? Zipp's website
says that the 404 wheels are compatabile with all Campy 9 and 10 speed
systems, so I definitely want to make sure I get the right cassette(s)
to use on these wheels. The cassette I am seriously considering for
its low range gearing is the Veloce 9 speed 13x28.

Thanks in advance for your help and advice!

Snip using Campy 9 speed cassette on 8 sp hub.

It is not a straight fit on.
People will say it is possible by filing away some bits on the
hub/cassette,and it is then held on the hub by about 2 turns on the lock
nut(the 9sp is lightly wider) - but is that really worth it?
Another way is if you can get an older (yr 2000?) 9sp rear hub, you can
take off the freewheel/freehub from that, and fit it to the 8sp wheel, and
you then have a 9sp wheel.
It may be more cost effective to just get a new wheel built up in place of
the old one.
All 9 and 10 sp campy cassettes have the same spline pattern, so there are
no problems with swapping between wheels.

The 9 speed splines share the outside diameter but have a smaller inside
diameter so they won't fit on an 8-speed freehub. Campagnolo built 9-speed
frehubs which fit the old hubs (I swapped my Chorus 8 speed parts for
Record-Ti 9-speed) although they're getting scarce (and therefore
expensive - say $100 for a Chorus/Record part).

Are there different spline patterns between the different
Campy 9 speed cassettes (e.g., Veloce and Chorus)?

No.

The 8sp cogs will not fit onto the 9sp hub. You can get 9 x 8sp cogs
onto the 8sp hub if you replace the spacers with 2.5 mm spacers. They
are sold by Wheels mfg and Shimano spacers and they are purple.
Someone makes or made an 8sp x 28t cog. That would be great to add to
a 12/25 cassette.

To use a 9 or 10s casette you need a 9 or 10s compatible freehub body so yes,
you need to make the 8s wheel 9/10s compatible. You may be able to find a
freehub body if the 8s hub is a Veloce with cart bearings. If not, may be tough
to find...or build a new rear wheel using a modern Campagnolo hub.
