Hey Scotty, I love your videos. Thanks for being my shop teacher as of lately. I have a 1960 Ford F-100 223 ci. 6 cylinder and I just did a pertronics tune up on it but I noticed the old and the new rotor buttons have play from side to side. I have the correct buttons for the d shaped dist. shaft is this not going to cause it to be out of time because of the play. Please let me know. My email is christspal@msn.com. thanks. Matt

generally they all have some play, but if too much, distributor is worn out inside

The dist shaft doesnt have any play its the rotor cap.

I'll send you a short video of it in a couple days Scotty. Thank you sir.
