Headlight question

This may seem like a silly question, but I am new to this. I currently have an 87 stepside with what I believe is single headlight. (1 square headlight and a rectangular light below) I like the look of the 2 headlights much better. (two same square headlights) How hard would it be to make this transition? Thanks in advance.

 

It's pretty much the same thing as swapping in an '89-91 grill: requires replacing the core support, headlight wiring harness, and the headlights/mounting hardware.

 

Ok I purchased the headlights, bezels, and new wiring harness. Where can I locate the core support?

 

Not sure if Classic Parts, LMC, or anyone else sells them. When I did mine I got the parts I needed from a junkyard.

 

Would this be it?
