simple...first get a flashlight and look at your harmonic balancer, (you may have to slightly turn the motor over by hitting the key a few times to get it to where you can see it properly)
there will be numbers, i think like 30-0-30. looking at the balancer from the front of car find the numbers on the right side of 0 (0---10---20---30). get some chalk or white out and put a line thru the number at which you would like your timing to be set. ex. 14*
on the passenger fender well close to the mass air meter will be a spout connector, a little grey square plugin...remove it.
hook timing light up to battery (pos.-neg.) and hook other clip from timing light to the #1 plug wire
loosen clamp on distributor
start car
point the timing light at the balancer, from a place in which you have clear view of the balancer, i can see mine best if looking by the upper radiator hose. hold the trigger on timing light. the light will flash quickly and you will see a small metal "pointer". grab your distributor on the cap and slighty twist it clockwise until your white mark is lined up with the pointer.
tighten clamp. shut car off
plug in spout
you should be good to go...you may have to adjust your idle accordingly
