thanks for the help, you guys are very cool. so i have the k-var in hand it was in the mail box when i made this post. it looks good but has a rivit instead if a screw, so is it not a good guild? should i send it back and get one from dinzag. the only prblem i see with it is i have never installed a hammer rivit before, and not to sure on what size hole to drill for it. the guide it self looks very well made though. sorry if this has been coverd before but i cant find to much info on the k-var guide here.
