1980 square headlight question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys I have a 1980 square headlight front end and I am wanting to switch it to the round headlight front end and I was wonder if the core support is the same or if it's different and what has to be changed to swap it to the round headlights thank you

Correct me if I am wrong but I believe the core support is the same for 73-80.

core support is the same, you need the headlight bucket and a round bezel set to make it work.

I thought that there was a slight difference when it comes to the holes for the mounting springs for the headlights.

all the mounting holes you need are already there, really easy swap-i did it on my '80 last year. you also need a different front valance and turn signals.
