4 head lights to 2

what's all involved with going from a 4 headlight setup (1989) to a 2 headlight setup (88-91)? I'm thinking:

core support
grill
left and right trim pieces

Anything else? What would need to be done with the wiring?

Re: 4 head lights to 2

I can't comment on the parts list, but it would prolly be cleanest/easiest if you find the light harness that matches the lights you intend to use. I have installed a four light system from an 87 on a 77 cab and simply used the light harness from the 87. The wire color codes were different, between the two years, but the pin out at the firewall plug was the same.
