It's been awhile but I seem to remember a small hex head looking bolt that sticks down from the assembly towards the front of the car. I believe the head was not much larger than the threaded part itself. Threading it in or out raised and lowered the headlight assembly so you can flush it out with the body of the car. As for moving it forward and back...sorry, have'nt tried that one yet. Hope this helps.

To center the lights the adjustments should be made at the pivot bushings. To raise the door to where it is flush when closed than you adjust the screw mentioned above.

ya THAT screw :mad . I have missing nuckes becase of the top of that screw is a regular type bolt head, that is 3/16th or something I believe. Well I managed to get my wrench up there to get the headlight perfect, then when I noticed the smaller one on the bottom of the screw....ugg...sometimes I overlook simple stuff :smash:

so when adjusting flushness, are the lights up or down? hood open or closed? do I lay on the ground and reach up somewhere?
thanks....

I assume you mean a quarter inch up when the light is closed. If you open the headlight and lay on the ground underneath the car looking up at the linkages, you will see a bolt head sticking out of the center linkage. This is to adjust the open position of the headlight. There is a bracket that the linkage attaches to that has 3 bolts that hold it on. One is underneath the linkage pin and the other two are on each outside end. This bracket has slotted holes where the bolts go in. To adjust the height of the light when closed you need to loosen these 3 bolts and slide the bracket forward to lift the headlight when in the closed position and backward to lower it when in the closed position. As far as moving the light ahead, it seems to me that the bushings at the rear of the headlight assembly have some movement in them. I think you can loosen these and slide the unit ahead. I would adjust this one first, then the close position height, then the open position height.

THANKS DALANNEX I ajusted the 3 bolts and centered the cover... looks great!!!! One last thing when I hook up th diafram arm,the one with the eye on the end of it the covers front edge is low,if I unthread that eye further out,it should raise the cover up? Is this right?I"m stoppping for today,too many sharp edges,its a good thing this car is red, it dosen"t show the blood!!!Almost as bad as the door handles to work on :chevy I tried to turn it nogo,Sprayed with WD-40 is this thing fragil? I was planning ti use a small pipe wrench to hold it while inserting a screewdriver in it to turn it? Or is there another way to unscreew it?Thanks Again

I am having a hard time understanding what you guys are describing. My headlights are fine when closed, but one side needs to go up about one quarter inch when open. Can you help me make this adjustment?

Default Re: Headlight cover adjustment (rdrman)

rdrman, The adjustment where the eye threads onto that rod is to get the proper amount of tension so that the linkage kind of "snaps" into place and locks up when the lights are up. If it is set too tight the lights won't lock up and if it is too loose the light will shake when you drive down the road. Open the light and look to see if the linkage is locked up. If it's not, you can try adjusting the single bolt. Back it off to see if it locks up. If that bolt is holding it from locking up, when you do get it to lock your headlight should line up. If that bolt isn't hitting anything when open and the linkage isn't locked up the eye is probably holding it back. This is when you would adjust the eye.

virtue4u, it almost sounds like one of the small rods that the headlight pivots on is bent. They are at the back of the headlight and have plastic bushings in them. I just don't really know any other way that could happen. I would think the headlight would be equally low when closed if everything was straight. You could also check to see if the whole headlight is actually low when open of if the bezel that goes around both headlights just doesn't line up right making it look low. Is there an unusually large gap at the top of the bezel, between the bezel and the top cover? Also, does the back of the cover on the side that is lower drop below the level of the body when open?

I'll check on this topic when I get home from work today. Good luck.

Actually everything looks good when closed, but the headlight cowling is 1/4 inch low toward the front when open. (For example, one headlight cowling is easily removed, but the other cowling is VERY DIFFICULT to remove because it sits too low.) I'm having a hard time understanding all the mechanisms operating the headlights, but it looks like there is an adjustment screw on the arms. I would love to adjust the lights, but I may be the only person who notices the "problem." Consequently, the old saying keeps coming back to me "If it ain't broke; don't fix it."

you guys are killing me... read this post cause I needed to get the drivers side headlight door flush with the body.. these directions scared the hell out me... but I decided to look anyway...

1. ensured the lights were down
2. layed under the car head first under the nose lined up with the light
3. looked up and saw one bolt facing the drivers seat
4. got a 1/2" wrench on the bolt, turned 1/2 turn
5. checked light for flushness
6. went in and drank a beer

try not to make stuff harder then what it is.... its easy to scare us new guys and gals

thanks though, 2 years later, the light is flush. :D

Default Re: Headlight cover adjustment (virtue4u)

Virtue4u, OK. Same problem I had with mine. It's been awhile, so this is all kind of hard to remember, but krafty said he adjusted the hex head bolt in the center of the linkage to get his closed position flush. If that's the case I was wrong in my previous post. I must have had my open position adjuster and my closed position adjuster backwards.(like I said, it's been a long time) But you said yours was low when open. Loosen the 3 bolts on the bracket that the eyelet hooks to and slide that bracket until the headlight lines up in the open position. Then retighten them and close the headlight. Now the headlight will be off slightly in the close position. Adjust the hex head bolt until the close position is right and you should have it. BTW, to get the center bolt of the three on that bracket loose you will have to remove the pin that goes through the center of the eyelet. You can't get a wrench on it unless the eyelet is out of the way. :bb :bb :bb :bb :bb :bb

On the side frame of each headlight assembly is an adjusting bolt with a
rubber cushion on the top of it. This rubber cushion makes contact with
the headlight frame and stops the upward travel. There is a lock nut
to loosen and the bolt can be adjusted enabling the headlight to move
up higher before the rubber cushion hits the frame.

Yes, the adjusting bolt on the arm will allow the door to open further, and you must tighten it to raise the door higher in the open position.
Another way to center the cover in the opening is to losen and adjust the bolts that hold the entire mechanism in. There are 2 bolts at the front(bumper side) and 3 at the back. The back ones are easily accessed with the hood open. Easy being a relative term; you can easily see them. The front 2 are hidden behind the front grills, which will have to be removed to get to them.
Here is what you do: remove the front bolts, the front of the light housing sits on the metal reinforcement of the front end so nothing will drop. Then losen the back bolts. You will them be able to move the light around at will. Once you are satisfied with the position, tightnen the back bolts. Then put the front ones back in.
This is the easiest way I have found to center the lights in the openings. Hope this helps. By the way, the factory service manuals have detailed steps for making all the adjustments neccessary, and I highly recomend getting one if you don't already.

later
