Toe alignment on my 32 RP

Unfortunately that puts a twist on the spring and loads the spring bushes.  Long since been an action advised to avoid.  I think you are thinking of castor angle.
A thin wedge between chassis nose and spring and possible re-location of radius arms rear ball joint if required is way to go for different CASTOR angle.
Believe king pin angle is that set by angle of king pin axle end to rest of axle.
