I have a 1969 Z/28 camaro. I have questions on the pulleys. I have water pump pulley with casting numbers 3932456DV, crank pulley 3956666AG. The research i have done says that the crank pulley is for a 307, 327 & 350. I have the DZ 302 engine. Are these the right two pulleys that go together, or am i suppose to have crank pulley with casting number 3956668CG? My 69 was built in the 3rd week of dec 1968. The research says that crank pulley 6666AG is PS< after 11-1-68. Thank you anyone to shed some light on this.
