According to Autozone's product page for the DWS kit: "3rd and 4th synchrony rings have an updated inner taper, 74.95mm inner diameter". So I'm fairly certain the CWS will not have these updated parts. I want to first see how many miles/what sorts of issues crop up with this kit and perhaps try the more expensive DWS kit in the future. I'm not 100 percent convinced that the older 89-97 spec parts are that much worse than the 98+ version. It seems like reports of grinding gears are just as common with the earlier spec, so who knows.
