Hey, my wife is 6'2" also, so I can visualize your problem.
In the first thread:

First try at the seat mount. Rear mount is simply a piece of 3/4" x 1/8" bar stock with twisted bends on the ends to mount to the stock rear seat mounts. Saddle sits above on the three inch springs. Front mount is simply a U bracket to hold the nose pivot of the seat welded to a flat bar that bolts to the stock front seat mount. (No modifications to the bike at all.)
Note how comfortable the wife now looks.
I'm a bit shorter, so I modified my mount to bring the rear springs about 3" down and 2" forward:

As for hardtailing, why? I cross railroad tracks on the way to work. Prior to the sprung seat I bottomed out the springs and had to pull my butt off the saddle to avoid a nasty jolt. With the sprung seat both sets of springs bottom out and I can remain sitting.
