Initial Caster Settings

I have been unable to open JTIS to see if there is a diagram indicating an initial setting for the shims to set caster on a 1997 XK8. Can someone please send me a diagram indicating which size shims go where as a starting point? Any help if greatly appreciated.

Thx,

The image l have is barely legible but Google will find it if you search XK8 castor or similar.
2 thick and 1 thin on front left and right rear position. 1 thin on each of other two positions. I think that layout may be for L/H drive vehicles but l have been unable to find diagram specifically for R/H drive vehicles but castor specs are definately different for each.
