I am trying to find our what shims I should I get or will the stock shims be sufficient?

 

What are the details? Lift? Shackle flip? Why are you replacing the shims?

 

I have a six" lift with the stock shims.

The reason I am thinking about replacing the shims is to correct the angle of the driveshaft and not have so much angle on the U-Joints.

 

Okay so do you have blocks or springs? Either way they have the proper correction built it.
Are you having excess vibration?

 

Blocks... Regardless

no all good there. Rides as good as a Bronco would.

My pinion seal started leaking close to the time I put the lift on. Maybe it was just its time to go. The angle looks sharp to me but that may just be me.

 

Can you snap a pic of it?

Here is a pic of mine with 6" lift by means of a shackle flip and add a leaf.
This is with NO shim at all.

 

No, I am in Taiwan til the end of the month. When I get back I can.

But my angle of the third member and the yoke is a lot more then yours.

How much was that driveshaft? I am still running the stock.

Mine only show like 2 (2 1/2)" of spline but I am worried about flexing out and one it coming out and dirt and that stuff getting in the diff.
