In the name of 'preventative maintenance and in dire need of something to do, I recently pulled the distributor from my 280s and rebuilt it. Problem is, I neglected to mark the orientation of the bottom drive in relation to the distributor shaft. Here's a pic of what I'm referring to.

Noting that one hemisphere of the drive is slightly larger than the other, if the larger is facing towards me currently, the rotor is in approx. the 2 o'clock position. Is this correct or am I 180 degrees off? Which leads to my second question.

When I pulled my dist, I didn't bring the motor up to TDC, just yanked it, thinking it would go in as it went out. Will I need to turn the motor to #1 TDC to get the dist back into place and functioning?

Thanks and Happy Holidays.
