Cassette Spacers and Spacing

Can anyone point me to a page that has spacing dimensions for Shimano
seven speed cassettes ?

I've got an old style 9 speed XTR cassette I'd like to drop two cogs from and
respace to 7 speed.

9-speed XTR cassettes have most of their sprockets riveted to spiders, and
can't readily be respaced. Are you sure your cassette is XTR?

Thanks for the link James. It is an XTR. The design changed some time in the
early stages of Ti XTR Cassettes.

One of mine has the two largest as well as the next two smaller cogs
attached to separate spiders. The other is as you've described it.

I've mounted it and it seems to be fine as is, shifting a 7 speed chain by
friction mode, but I could imagine under load the chain may prove to be too
wide.

5mm ctr cog to ctr cog..measure the cog thickness and use a spacer
that does the 5mm c-c thing.
