I have had to do that before, Lol
Yeah, there should be a notch or at least a line on there, if not, take out the #1 sparkplug, put a long screwdriver in the hole, and turn the motor, By Hand!, and wait untill the crewdriver comes up and back down again, when it is all the way up, thats TDC(or 180 out)

It will be at either the compression or exhaust stroke, if the truck won't fire at all, it'll be 180 out, or on the exhaust stroke.
So you know the rotor in the distributor is pointing 180 degrees the wrong way.
So you have a 50/50 chance of getting right the first time, if it doesn't fire, you know it's 180 out(if everything else is working correctly

Put your finger over the #1 plug hole as you turn the crank. You can feel when it is all the way up - within a couple of degrees.
Tip one is move the wires if you are out of sync; don't keep pulling the distributor. For some reason people think the distributor HAS to be in a certain position and it doesn't - think it through and you will see.
