Art,
I don't know anything about seat track extenders, but I know a trick to gain a little legroom. There's a black plastic footrest (under your left foot) which can be removed. Just get your fingers under the left and right edges and wiggle back and forth until it pops up. You can slide it back on if you don't like it, but I think it's better.
