Idk much about this stuff or what any of those numbers mean.. I need a crankshaft pulley for my 72 GS 350. Tried uploading a pic from my phone but it won't work. It's a double pulley, for the alternator and a/c I'm guessing (it's an a/c car but currently no a/c). Then behind it is a smaller diameter pulley for the power steering, then the harmonic balancer. Do you have what I need?
If you have an A/C car your car would require Pulley Number 1235821. This is a 3 Groove Pulley for a 350 w/Air. Maybe use the search engine and search that number. You may find one for sale or possibly somebody reading this may have one.
I'm sorry, I'm confused Todd. You are saying that 1235821 is a 3 groove Crank pulley, and 1235822 is a 2 groove Fan pulley?
