I just installed halogens in my 66 gmc, had to do the mods for the clocking, also had problems with those little plastic things that one used to adjust the headlights with. bought new bolts and just used standoffs that were the proper length, one end make threaded to fit in the grille surround, the other a female threaded part. Will hold up better than plastic and did not cost much. Kieth
ps if anyone needs the information I will take pictures and docment the sizes of the stand offs. Kieth
