I believe the 80's are narrower, just from looking at them. But with enough fabrication its certainly possible. Fenders and radiator cradle I would think. Plus getting the 80's fenders re-shaped to match the contour of the door. There would also be the problem of the differing body lines between the front 80's fenders and the rest of the truck. Sometimes it works and looks good. sometimes it looks like an amateur welder went crazy with a sawzall in a junk yard. ("The fins from a 58 Edsel station wagon on a Geo Metro with a Model T front end. I could pull that off!")
Maybe I could just fab my own grill outta mess but use the circle lights and a custom bracket? I just hate the 90's front end on a 2wd
if you dont like the 2wd stuff, what about the 4x4 or 4runner fronts? they are pretty easy conversions. anything can be changed with enough time and money. there have been LOTS of front end conversions done to these toyotas over the years, start looking around on here and other forums, at shows, and in MTM for ideas. if done right, the 4 round headlights could look good, but they way the grille is done on that truck you posted a link to, totally kills it.
