incorrect, other than the swiss cheese frames in 80 and 81, the frames are the same from 80-91,
in 87 they began using brackets on the bumpers that mount to the side of the frame horns instead of bolting through the fronts like the 80-86 but frames are the same,
they changed drastically horn wise when 92 rolled around with the obs, here is a link showing 87-91 bumper and brackets
towards the bottom is the post with the pic of the brackets
