8 speed campy w/ XTR CS-M900 cassette

Sorry for having to ask a campy compatibility question...

I recently purchased a 1996 campy 8 speed titanium ergopower record group
that came with campy 8 speed record cassette and a shimano 8 speed
hyperglide 12-28 XTR CS-M900 from 1998. The group came with a 9 speed chain
and apparently has worked with the XTR cassette. Since 8 speed campy hubs
are rare, I would like to believe that the XTR works. Obviously I do not
have this group mounted on a bike or I would know if this works. So my
question is: does anyone know the spacing of campy 8 speed and shimano XTR 8
speed? Side by side, the 2 cassettes look similar. Thanks in advance for any
help. Eric

1-is this a known fact? Has anybody tried this?

Sheldon Brown knows. See his site at URL:
http://sheldonbrown.com/k7.html Scroll down or click down to "spacing"
Campy 8 speed spacing is 5 mm while Shimano 8 is 4.8 mm. I wouldn't use
a 9 speed chain with either. You might get by with it on the Shimano,
but why would you try it for the price of an eight speed chain?

short answer="no"

As posted here earlier in the week, Campagnolo 8 spacing is
5.0, same as Shimano Seven. Shimano 8 is 4.8

Not only is the spacing different but the Shimano XTR
cassette cannot mount on a Record 8 hub.

You can change the Record lever to a nine with a new shift
insert ($34.95), get a new model Camoagnolo RD (from $57)
and a Shimano wheel ($?.00) for your XTR cassette. That
comination is excellent with Shimano 8 spacing.

Other variables include moving the cable attachment position
to change the RD travel but I am not an expert on that. See
hubbub.com.
