Does anyone know what the differences in edge chaincases were and which sleds had which chaincases? Were there three different chaincases, standard sleds, RMK, and Vertical Escape? Seems like I remember there being a difference in the standard RMK chaincase and the vertical escape chaincase but I may be mistaken. I was looking to buy a chaincase just to get the dimensions off of it but am not sure which are the same as mine. I have an 03 RMK non-VE and am looking to do my own extended chaincase on it.
