if i'm correct them green lines on the sides came out in 76-77. my friend fix up a 77 5000 and is now drag raceing it. if you take out the suspention be careful with the crossaft becuase if you break the blot it take a long time to fix. just thought to tell that, just in case becuase it's a real head ac.
76 and 77 were the last two years of the Kawasaki powered El Tigre. It looked like a hopped up Jag.
