I've installed the shaft, remembering to put the shims back in the correct order.
To install the drive, you need to add those shims back and make sure you are putting the drive in correctly.
The drive has a tab that is offset and if you put it in wrong, the distributor will be 180 degrees off.
The correct way is to have the larger half of the drive toward you and the notch for the rotor pointing northeast.
Now drive the roll pin back in. I use my vise to slowly force the pin in.
When it's flush i use a center punch to finish the job.
