Yep Lumbar and leg support adjustment on DS only,
I did move the seats back a few inches and drilled the holes in the flat bar. need leg room because im over 6' tall. I might add some support in the rear because it hangs over about 2.5 inches. They are very solid now though.
The seat is adjusted back pretty far in this picture more then enough room for the passanger/Driver no matter how short/Tall you might be <img src="/forums/images/graemlins/smile.gif" alt="" />

I imagine you'll have to fab that support. I've seen some bouncies with another support (factory) welded on the rear.

Is it uncomfortable to get over the thigh supports on the way in and out?
