Self-induced distributor dilemma
I foolishly removed the distributor and vacuum advance from my 81 f-100 (v8 255) without marking the position of the rotor, etc. I was in a hurry to get to NAPA before they closed and wanted to bring in the old one to avoid the core charge but...I know that's still not a good excuse. However, NOW I need to install the new one. Can someone walk me through the procedure for installing a new distrib. without any reference marks?

Here's what I did to recover from a dose of dumb.
Put a mark on the body of the distributor where the #1 terminal is based on the cap. Watch out for tricky caps that mix up the order.
Roll the engine to top dead center on #1 cylinder. Make sure it is TDC on the compression stroke instead of the exhaust stroke. A finger on the plug hole worked for me.
Install the distributor and rotor with the rotor aimed at the mark made in the first step.
Put the cap back on and give it a shot. You should be fairly close. If it starts, set the timing. If it backfires or otherwise misbehaves, you may have it 180 degrees out of phase from using TDC on the exhaust stroke.
