I was looking here: http://www.cjponyparts.com/Category.aspx?ss=&c=10020250&sb=&pgnum=1&pgsize=all They list the 69, 70, and 70 Shelby as three different parts. Any idea if the 70 Shelby spoiler will work? I like the look of it better I think.
The difference is usually the material, I've looked at Branda, they have plastic, and fiberglass. I would think the plastic would work the best.
The 69 and 70 look pretty similar, but the 70 Shelby looks a little smaller (same width but lower profile) with different corners. I think I like the look better.
