Constructing a "spark gap"

I have a unique requirement for my current design. I have 12 data input lines that need to have ESD protection.I thought I had this problem solved with a zener diode array but the customer wants a "spark gap". This is supposed to be a small triangle of metal positioned 6 mils from the pad (oh, yes, the spark gap is between pins on a connector) on 2 oz copper. I've tried making small shapes (like testpoints) but that doesn't seem to work too well. Any ideas on how to handle this?

Cheers,

Tomo,
I understood what you meant. The board shop was rather hestitant about 6mil spacing on 2 oz cu. We were successful in manufacturing of the board.
