bought a running 1965 GTO with a 1973 455 motor with 62 heads and the '65 Tripower. there is only one belt on front of motor running alt. power steering, waterpump and balancer. balancer and water pump are double pulleys. I think it should have two belts but it doesn't line up for two belts. this is the only way pulleys line up. not sure what was used for pulley, brackets, pump. what should be used on this Frankenstein to be correct? thanks..
