I I have a 63 ford falcon it was stock with a 6 cyl. And someone put in a 302. Not sure what year. The alternator and gooseneck match a 69 mustang. Anyways. Someone put in a electric water pump. Car is running hot. I have a electric fan. With the electric water pump. My alternator can't keep up with the drain of the fan and pump. Along with the overheating issue. I am looking to replace the electric fan and pump. With original mechanical ones. I have 6 rib alternator pulley. With 6 rib crank pulley. I can not find the correct water pump pulley. I am going crazy trying to find a 6 rib water pump pulley, For a 302. Am I wrong that it came out of a mustang? There is no A/C or power steering. So I need a pulley with 6 grooves. I would really appreciate any help.
