blazer k5 headlight up grade

i have a 79 k5 that has an upgraded front end off a 91 blazer and it looks good but i want to replace the the duel lights with a more modern single light from a newer blazer. can anybody help? I need tips please

Do you mean the composite style? Like mine? http://adepssimius.is-a-geek.com:81/rob/Blazer%20RF%20corner%20shot.jpg

yes like your's

Find a chevy truck in a junkyard post 93 and you should find similar headlights. They should match up, maybe a couple mods, but i think the wiring harness will be the same.

my truck is the old body style the k5 full size. i bought the lights for an 88-93 thinkin they woul fit but it didn't, a friend said that the light off a monte carlo might fit. the monte carlo came with a one pieac head light at one time.
