Call Justin direct at Dragonfire. I am not sure how the base steering wheel attaches but the XRS already has the same 6 screws you see in the photo. I just removed the screws, swapped steering wheels, and replaced the screws. It was literally a 2 minute job.
Pop open your steering wheel as long as you have those same 6 screws your good.... You may also want to order the XRS steering wheel center cap. I just popped it out of my stock steering wheel and it fit perfect. The Dragonfire steering wheel doesn't have a centercap.
I got the quick release from dragon fire. Just bought the adapters, no steering wheel though. tightening the bolt back on to the spline will be a task as I modified a deepwell socket by slowly grinding down the end until it fit over the nut.
