C2,yes you will have to drop the aux tank.<br>Install is easy,I did it in an afternoon.<br>And yes,the supplied screws work just fine.<br>Hardest thing about the whole deal was cutting the ends down,because I have cut fenders.If you do it with a hack saw,it will take forever.I used the chop saw at work.<br>Thanks for the info about the 2 piece design Ipsolo.Sounds kinda like a cheesy design,sit a rocker on a rock,and the 2 plates would probably spread.BC skis are U-shaped,much tougher.
