I am thinking of swaping the footpegbrackets from an S2r/S4R onto my older S4 for looks. Has anyone done this before? i dont want to change the swing so need to know if the swingarm pivot shaft from the single sided swingarm will fit into the older double sided one. I have seen that it is longer to accomodate the footpeg brackets. Also do the endcaps which fit into the brackets screw into the pivot shaft?
