So, reassembling 4 F headlights , but- bad move -we had put loose headlight buckets and misc parts from 3-4 cars in a box , plus some had the “ factory unit” of the rear mount plate and the head light bulb holder stamping separated . The stamping has depressions for the bulb , the bulb only goes into it one way . But stamping has to keep bulb top up in car as other stuff rotates . The rear plate fender bolt pattern rotates in the car , only goes on one way but , while same rotation is in two places sort of opposite directions ( inner and outer pairs), due to the tab that sticks off it with nylon nut to hold chrome cover , they look the same but are location specific — maybe once assembled - to keep bulb top up . Sounds easy right ? Well there are at least three different bulb holder stampings to keep bulb rotated straight up as bolt pattern rotates , (why three and not two baffles me still) . I had three stampings in front of me slightly different , a few of each. Add into that the cover tab location rotation is the same , say for outer driver and inner passenger , and you can be driven nuts for hours . All fits , but bulb may be tilted . It gets like which cup of about 12 is the peanut under , after you happily put them on without bulbs the first time , get a surprise later when you mount bulbs . Careful thinking seems not to work well if they have been apart unmarked . Anyway , Two rules : mark parts with top ( T) and position 1234 , if taken apart , and 2 ) never mix unmarked parts from several cars in a box . On and off car 2-3 times 2 hours later . Only 15 minutes of work , 1:45 trying to figure it out . Not sure how , but now ok , mostly lucky trying .
