Hello, I'm Jason and will be helping you with your Isuzu question today
So, the tail lights from the Chevy Luv, starting in 1981, through 1982 will work
And all of the Isuzu pickups from 1983 through 1988 have the same taillights
If needed, I can also provide some sources for these lights
thank you very much Jason you have been a great help for me.
