1991 GMC top kicker w/ towanda 366. Someone puled distributor and wires. I need firing order and #1 cap location. thanx

if you haen't got it fixed yet, #1 is at about the 11:30 position on a clock with 12 being teh very front of the engine. It should kind of point to the #1 cylinder. the firing order is 1-8-4-3-6-5-7-2 and it fires clockwise.
