To me it looks like the same fender but it looks like the area around the turn signals on the front end of the 90 or curved more toward the rear of the truck and it looks like the 87 is straight down. Maybe I am trippin will just one fender work or do i have to change the whole front end and are the hoods the same or different.
87s more square. 89 and up is more round. starting from 89-95 they changed the body style of the trucks. It became more rounded.
