Easy job, i can talk you through it if need be. They reccommend 1 spline so i did my first mog 2 splines, looked great but not too practical, did the candy apple one 1 spline and that drove fine but i would have liked it lower. If you lower the front 1 spline then raise the rear its the equivalent on 1.5 splines and that seems ok (i did that on the white traveller that simons sons got) when your ready let me know and i'll PM you the details.
