Heres the normal 8-9" arms at Chevs of the 40s. Scroll down to see them. If they arent long enough you could make a small bolt on arm extension.
But be warned, these are not steel like the originals, their either aluminum or pot metal. I ordered a few for my COE and broke the bottom ear off the passenger side when I was tapping the hinge pin through. It just needed a little wiggle to align, but I didnt have any warning, and it snapped right off.
