You've got the long legs.  I don't have measurements for the difference between the two.  I think the original was designed to accommodate a 70" prop and the later revision will accommodate a 72".  This is in order to have a certain ground clearance as specified by Van.  I think it's 6" when the fuse is level.

You have to go back to about the mid 90s to find the short legs.  The long legs were a revision to accommodate longer props on 180 hp engines.  The original RV-4s were designed for an O-320, not an O-360.  Then all those old ex-hot-rodders got into building airplanes...
