I dont understand why you would need that unless you took off all the wires and took out all the plugs and forgot how the wires were.I have the same truck and I always do the plugs and wires one at time to make sure I make a mistake.If this is your ploblem let me know because i might be able to walk you though it.

ok number 1 piston should be a top dead centre & mabe on the top of the cap is a mark or number
if not then there should be a mark on the lip of the dizzy!
if not then just choose one near the front & set the points at that point on the point of sparking! [ready to open points] make sure you have spark or you may have left ou the insulator on the points locating pin!!!
then its a matter of the firing order!
i hope this helps
cheers Rob
