I just received a shifter extension from Illium Works, and it's a really nice piece -
They are sold by other dealers but those dealers charge more for shipping ($10) than Illium Works ($$6) so I bought it direct.
I bought it because I found myself having to turn my leg in towards the shifter to shift. This extension will extend the stock shifter by 3/4".
I'll post up a photo later today when I install it.
