I know the Kirkhams are symmetrical side to side. Specifically I was interested in knowing the differences between the CURRENT AC bodies shelbys and the Kirkham bodies Shelbys. For example:

-any differences in the alloy used?
-thickness
-styling differences-for example the radiator opening on the Kirkham bodies appears flatter. Likewise the front wheel flares. The rear wheel flares appear more pronounced on the Kirkhams but I could be wrong about this.
-are the tolerences of the current AC bodies better than 45 years ago? Are they more symmetrical side to side.

I realize many of these points are splitting hairs and require a fine eye.

Thanks
