Default Shims on cpt spring kit

The shims on my new cpt spring kit on my 67 800 appear to be pointing my front diff downward Iím having thoughts this is making the drive shaft have a bigger angle? Any thoughts,Iím not sure how to post a pic

The only way to fix the bad caster associated with lift springs is to put those shims in which will point the pinion down but will rotate the C's to give you better caster.

You get one or the other unless you're willing to do a Cut and Turn on the front axle. That way you can put 4-6* of caster in and rotate the pinion where ever you want if you also cut the spring perches off.

If the kit came with longer shackles, they will tilt the differential pinion up when the front of the spring is lowered, and also rotate the outer "Cs" forward - which is bad for caster. The shims correct the caster, which keeps the Scout from wandering. The bigger drive shaft angle comes largely from the lift. Make sure you jack up the front end so the front wheels are hanging at full droop, and rotate the front drive shaft to make sure there is no binding of the u-joints. Usually not a problem with a 2" lift but a problem with a 4" lift.
