BMAN said:It's for a 64 FJ45LV. Here's what I know. Mike calls me up and says that he needs a nut for his crank pully. I oblige and aske here. Treerootco steps up and sends me one for nothing (thanks Root). Mike takes it home and then calls to say that I doesn't fit. The nut is a stepdown shank type nut and the pully isn't. Also with the pully in place there's barely 2 or 3 threads showing. I'm assuming that the pully is wrong but I'm unsure. I have a nut and pully on my 67lv but the nut is round and w/o a working e-brake the motor just turns when I get after it.
If the engine is the original early F engine, then it won't have a nut holding the pully on the crankshaft. These early pullys are pressed on. Since the crankshaft isn't threaded, putting on a later model pully still won't allow use of a nut.
