[DeTomaso] Water pump pulley

[Kurt Byrnes]

I'd like to use a single groove crank pulley to gain a little bit of 
room between the bulkhead and engine.  Does anyone know if there's a 
water pump pulley that would line up with the rear groove of the crank 
pulley?  Also, is there a single groove crank pulley available that only 
has the rear groove or do I need to modify a two groove to one?  I don't 
have A/C installed.

Thanks,

Kurt
