try www.autozone.com and go to vehicle specs. If you just want to adjust your static timing after disconecting the sparkplug wires you don't need the number one position. here's what you do.

remove the distributor cap and see where the rotor is pointing and to which direction it rotates.this will help you determine which "point" will fire next.put the cap back on and which ever point on the cap is the one firing next, that will be your number one position. since the distributor turns on a loop it really would make no difference which one is your number one. all you got to do now is follow your firing order,re attaching sparkplug wires accordingly.

AnswerWith the #1 piston at top dead center on the compression stroke, the rotor will be pointing to the #1 position on the distributor.
