My 88 Silverado Burb has the 4 headlight system. I want two headlight system so I can use my retna buring H4 Hella's. Looking at pictures the grills look the same between 2 and 4 light. Just looks like I need the Bezel and headlight buckets and possibly the turn signals to fill the gap. Am I right or am I missing something? I know 89 is different but what years ran the same grill set up as my 88?
