The OE 68-72 big block short water pump pulley setups found on these trucks used either a
6 3/4" #418 w/o ac or a
7 1/4" #414 w/ac two groove inner crank pulley and then a separate add on single groove 6 3/4" #525 outer crank pulley for driving the p/s pump single groove pulley #537. Are you planning on running ac, what are the last three digits on your w/p pulley? Your w/p pulley is going to be a factor in which inner crank pulley you can use, w/p pulleys #648, #789 and #797 are the OE big block options. If nobody above can supply you with what you need, I can do any of the above listed combo's for $40. per pulley, already pulled and ready to ship out USPS priority for $12.35 w/tracking. Let me know, Mel.
