Driveshaft angles... What size shims?

What size shims should I get?

08 Dcsb 4x4, ome 885 in front, ome rear shocks, icon aal on stock leaf spring.

Working angles from front to back.

Tc to first shaft, 4.7
First shaft to second, .5
Second shaft to rear pinion flange 3.0

Thoughts? High speed vibes starting at 40 mph. Can see bed shake in side mirror and feel it.

Thanks

You're rear working angle 3* should match the middle working angle 0.5*. Sounds like a 2.5* axle shim is in order. The front working angle is just an oddball.

Extra: some relevant info

 

I have heard that the shims don't necessarily translate to and exact change. How do I know if my center pins are long enough? Thanks

 

I believe most shims come with new center pins. I'm looking to get some as well.. I lifted the back 2" so I figure I will just get 2' shims and go from there..
