To run just the grille and headlights, you can modify your core support to accept them, and it will all look pretty good with the stock 84-88 corner lights- the chrome trim won't quite match up, but unless you're willing to make some significant sheetmetal mods just to run 92-95 4Runner corners it's not a big deal.
Another option is to just shave the corner lights completely- less bodywork than the conversion, and even more custom!
You'll also need to convert the H4 plug that your truck's headlights use to the 9004 plug that the 4Runner's headlights have. Each has three wires, so it's not too hard to convert.
Good luck with the swap- post pics when it's done!
