Well it’s a tough question. There are 2 answers I believe but not 100%. We used the k-series axles and just swapped side to side the inner joints. Which requires the upsizing of the wheel hub to 36mm hubs. I have heard you can use the RSX base model axles that have a 32mm shaft and leave the OE 32mm Hubs alone. Maybe a budget option. But I don’t know this from experience.
