I also have a 99 xc 600 with xc-10 front and I measured and compared and the lower radius arms and steering arms measure the same. My upper arms are longer but to use the shorter arms I have to relocate the mounting holes. The trailing arms look similar do you know the differences, and I have a torsion bar and not the sway bar so I would lengthen the connecting heims to make up the height difference. Does anybody know the length of the xtra 10 front shocks I think they are 15.5 but not sure.[?]
