    I have to ask now that I've seen it a couple of times, what is that "Nasty mice ball raping" thing about?

    COLLISION was nice enough to help me with this same issue a couple of weeks ago. /forums/images/graemlins/thumb.gif Do a search for "RPO option codes", quite a few of these codes were on my list that he helped me with.

    The ratio code is GT5 = 4.10 gears
