I bought my wife a used 2003 Summit 800 that had a badly bent lower right radius arm. I have the new part to install, but the previous owner had obviously tried to make the sled rideable with the bent arm. Does anyone know off hand what the measurements are for between the skies front and rear? Or at least the difference in the measurement? The fronts should be just slightly toed-out I think, is this correct? This is our first year with sleds, so forgive my inexperience.
