Crank Pulley ?

[67coronet]

Anyone know if the crank pulley from a 318 poly will fit a 76 360?? I seem to be missing my crank pulley (Thanks SpeedDragon!!) and the only extra I got is from a poly. I may have to go to the JY and find one. The pulley grooves line up but the bolt holes seem slightly off. I can get them all in but the last one is slightly off and wont go. I have spun this thing around and tried it all different ways. Is there a trick??

In about '72 the crankshaft pulleys went from an even spaced bolt circle to a pattern that has one bolt not evenly spaced on the LA engines.... This is why one bolt of a '76 pulley won't align. A rat-tail file or rotory file will cure this.
