The 84 SD has an aluminum hood, don`t know what other years will fit, and are aluminum.
Some of the 126`s have a steel hood, but I think the hood latch is different. I believe the gassers have the steel hood.
The SD has the latches on the sides, and the gassers have it in the center.
I may be wrong, one of the big guys will straighten me out.
