57 to 59 9 inch, at 57 1/4 wheel mounting surface to wheel mounting surface should work ok. The 64-66 Mustang 8 inch, which is the same length is also a possibility.
The Maverick 8 cyl is the shortest ( I think about an inch narrower), next are the ones listed above. There are companies that can make a custom length if you got the bucks. The Granada is about 1 inch or so longer.
Regardless of which you use, you usually have to relocate the spring pads.
