Campagnolo cassette mod?
I have a wheelset which has one of those campagnolo 9speed hubs with that weird little notch to fit the 9 10 11 speed campy cassettes. However i have campagnolo 7speed downtube shifters. Is there a way to mod the cassette by only assembling 7 of the 9 cogs and using spacers to fill the slack on the hub making it now a 7speed? I didnt see it but maybe you guys know of any campagnolo 9speed downtube shifters?
I want to avoid buying a 7 speed wheelset or upgrading to newer campy brifters on my vintage bike just to accommodate a campy 9 speed wheelset i already own.
Im trying to keep my Italian vintage all campy

Sure, lots of things are possible. 
Sheldon Brown's page says that 9-speed Campy cogs are 1.75mm thick, so if you can find (or make) 3.25mm spacers, that will bring it to the 5.0mm spacing used by most 7-speed systems. Campy 9-speed spacers are 2.8mm, so I wonder if an extra 0.5mm of material added to each one would be close enough. You would need another spacer behind the cassette to bring it up to the 38mm width needed for the lockring to torque down the cassette stack properly.
Apparently 9-speed Campy downtube shifters did exist.

spotted these on Ebay... 9 sp. bar ends... and there's a pair of Victory 8 speed Downtube shifters on there, too... no 9's right now......

i've always preferred bar ends... easy on uphills, no reason to remove your hands from the bars, no twisting your lower back... etc...
