Ruud, you have a fantastic car, very nice looking and certainly adventurous to drive as well. A really rare SWB car in perfect condition.
So far I know the long wheel base 911 were designed since 1969 to make the drivability better for a bigger number of drivers - same story as today - find more customers with a big wallet and smaller driving skills.
The two pics below may help to show the lines of the earier SWB cars, an aesthetically very balanced design, compared with the cars built from 1969 on, which are not too bad in their own, but the earlier car has this certain lightness and is so charming.
As you can see the LWB is not only realized by just taking a longer hood. All relations of the redesign had to be considered.
