Rivco Boards installed, now need to extend shifter

[raytracer]

I like the Rivco drivers boards but now I cannot shift near as well with my size 13. Looked at the Rivco heel/toe shifter, but not sure if that would be better or worse. Does anybody know of an extended shift lever?

Should be able to adjust shifter. Check stay screw. Should be allen wrench.

I can adjust it up or down, but to be comfortable I had to adjust it all the way up. This left it in a position where it couldn't get much leverage on the shifter linkage and made it hard to shift. What I need is to have it extended forward (towards the front tire of the bike)
