Thanks to you both. I think I must have xr4x4 hubs then, I THINK the carriers might be different too.
My bells on the reyland kit are flat. It is my spare standard 4x4 cossie discs that have a larger offset than my current discs on the car. I bet I also have the XR longer driveshafts which might explain the front vibration when turning.
Now to track down the parts I need!
