86-93 are all the same. Only differences being 4x4 sheet metal.
I think 85 down are narrower...but haven't took a tape measure to it.
Any other front ends would be completely custom fabbed.....except....
If you could get an Aussie/NZ/maybe european front from a ford courier. Good luck getting it though. The mazda also continued the 86 body style for a few more years in other countries....including a differnt front. It kind of looked like the newest mazda trucks, but was made for the older body style trucks.
Any way, good luck with updating/retroing your truck.
