Front grill ?
 

Just out of curiosity, I was looking at an '86 stepside. I really didn't like the stacked dual headlights. How difficult is it to swap grills and headlights from and older model with single headlights?

core support out . easy job tho . has to be 81-up tho for the swap . if you want round headlight = whole front clip swap and some work .

but once you drive it at night with 4 high beams on you might rethink the swap .

Very easy, mine was with single light swapped it to dual lights. Just buy the whole front core support with wires, loom, head light and parking light, the grill is the same no need to change it.
Must be the same year (85-87),
I hope this help. Capt J
