Just bought a really straight high option 1980 K20 with square headlights. This is my wife's truck since I have a 72 K10. She prefers the round headlights that was also available that year and looking to change since we're stripping down and doing a paint job. I've not been able to confirm in my research what parts are actually needed to do the swap. Is it just the bezel? Core support? More?

Radiator support, buckets, bezels, lights... I had an '80 Sierra that was round & was wishing it were a High Sierra or Grande with the rectangle lamps. I always liked that one year only upgrade.

Blasphemy…

You must be registered for see images attach


Just kidding, the core support on mine looks like it would accommodate round lights.

You’ll probably need the bezels, buckets, headlamps and parking lights, not totally sure though
