79 truck questions

Jd340 is right. the two round headlights came on lower optioned trucks and the four rectangular lights came on high option package trucks. that is why you will see 1979 Lil Reds with four lights and some 1979 Warlocks with only two. but as far as swapping on a 1978 grill on your 1979, the core supports are different. a round light '79 has sheet metal stands that hold the light buckets. put a '78 grill on and the headlights will stick out too far. :shock:
