Larry is correct...
The plug is like "Hens Teeth" they used to be reproduced however my source no long makes them. Had a few then sold them as I thought I could find more.
The pulley I am told is even harder, its a press fit one piece unit. There was a guy making them and was told he is also no longer going to make them. And his last few in process spoken for. Also = $$$$$$$$$$
Also, the Autolite stamp is not correct for 289 cars....
Sorry, these things are getting harder to find than one may think...
Apologize for being of no help.
