    it actually shows up as an '86... if there is no regulator yours is a nine amp... 5454 A7 is what you need.... if its a 5/8 you can run ANY 16 amp stator with or without a regulator... some say that you can't run tha 16 without a reg but with good battery program it won't hurt a thing.. if you...
