I actually have a shaft with 3.0 pitch drivers (not extro's) on it. One driver got bent when I landed on a rock a few years back, but your welcome to have the whole thing. I did try to straighten it, not too bad now.
Don't loose to much sleep over Extro's. I run my '03 right now with no Extro's, and if your suspension is setup correctly, you don't need them.
