Now I've received some stuff I ordered from WFO-concepts.
(The steering arm spacer is for my dodge

)
Since the axle doesn't sit in the center of the spring when using 56" springs,
I've really needed to adress my front pinion angle.
First I measured my caster-angle, by measuring the angle of my steering arm.
It was 12 degrees, and I think it's about 8 degrees stock.
I've heard that some people have as little as 3 degrees, but I bought 6 degree shims, so I would get 6 degrees of caster.
Since I have a dana 60 I need two shims for the passenger-side,
so the bolts or studs goes through the springplate at right angle.
I choose to get them from WFO, since they designed them to be bolted to the springpack with the centerpin,
and also because all others I've seen only sells them in pairs.
Unfortunately the recessed area wasn't big enough to fit a M10 nut
(I'm using class12.9 M10 bolts with grinded heads for centerpins)
So I had to mill that out on one if them.

But they have informed me that they will fix this in the future.
I also decided to add a pair of slightly shortened overload leafs while I were at it.
I soon realized that the centerpins gets sligthly relocated because of the angle-shims.
So I had to mill out the centerpin holes in my spring plates some

I've done the milling myself this time, if you're wondering why it looks like crap
You can calculate how much the centerpins moves, so you don't have to guess about how much to mill.
Just to show of my wicked MS-paint skills, I made a couple of drawings
Driver-side:

The centerpin moves forward according to this formula:
D=R*sin a
R=the radius of the axletube plus the height of the spring perch (11cm),
and the angle "a" is the same as the shim angle (6 degree)
So, D=11,5mm
And the passenger-side:

Here the centerpin moves BACKWARDS instead
D=L*sin a
L= The thickness of the spring-pack measured along the centerpin (in my case 8cm),
and the angle "a" is still the same as the angle-shim.
So, D=8,4mm
I've also cut down the kingpin-cap and welded it to the steering arm,
as I should have done from the beginning.
Thanks for the reminder, MTBLAZER89
