PA-18 Seat Options to Increase Headroom?

OK - I know I'm not the only tall pilot here (I'm 6'5") and just fit in the front seat of a stock SuperCub with a non-folding front seat. My head still brushes the X-brace and I've padded that with pipe insulation (the brace not my head).

My question is without an STC are there any cushion mods (lower/thinner cushions), seat slant tricks or seat frame changes (back to STCs) that would give me an extra inch or two for long cross countries and turbulence? I even took the button off my baseball cap and slouch as much as possible.

Thanks in advance.

At 6'4" that cross bar is the # 1 reason I always wear a helmet.

Shorter cushion or a Tango Cub seat that were built for the Air Force and were lower for a seat chute. Inboard flap handle attachment would have to be addressed.

My Tango cub's greatest feature was the lower seat. I really miss it!
