changing from sealed beam grill to halogen grill

I have a 92 k2500 that I want to change out the seal beam grill. Will a grill from a 91 that has the halogen lights swap right in? I am slightly new to swapping body parts and don't want to get in over my head.  

drop in on gm parts sites  like gm parts giant dot com  look up and print out the parts lists and diagrams for both truck grill and core support sections...  compare part numbers..

there are more than a dozen different online parts catalogs..

if your headlights are glazed over ..  there are ways to polish most of the lenses  back to almost perfect...

replacement headlight assemblies are available... i have seen some really cheep...
