Just got a '80 1/2 ton 4x4 shortbed!!!!!! Been searching for a reasonable one for 7-8 months! Now that the wheels are already turning, was wondering as I peruse the JC Whitney catalog. It has the round headlights, & I would like to put the 4 squares on it like my '87 so they look alike. My question is: Can you change headlights without changing the grill, or do you have to swap it too? Also, do you just unbolt/cut the round bezel housings out of the frame & bolt/weld in the housings for square headlights? How involved of a process is this? What about wiring also? Thanks.
