GTV6 AC condenser fittings

[Joe Elliott <jee@domain.elided>]

Does anyone know what size wrenches I need for the fittings on the 
GTV6's AC condenser?  I know I have a leak there (because I didn't 
replace THOSE o-rings, because the fittings were seized up when I 
resurrected the AC), and I'm going to have a limited amount of time 
on Saturday between getting home from school and setting off in the 
GTV6 for the U.S. Grand Prix--I'd like to be able to fix the leak, 
replace the defective (currently bypassed) high pressure switch and 
recharge it without too much fussing with adjustable wrenches.

Thanks,
Joe Elliott <-- at school, should be doing homework

'73 Opel <-- in friend's basement, about to sic my brother on it with a grinder
