Bringing this back from the dead...just now getting around to doing this.

Do I need a Pinion Shim Kit? Stylin Trucks is saying I do. Couldn't find a definitive answer from a search.

Well, I had a buddy install the shackles last weekend. We had our fingers crossed that I wouldn't need shims...AND crap...I needed shims.

My truck now has a noticeable vibration from 10-30mph and 65-80mph. It is REALLY noticeable if I accelerate aggressively. Ordered my shim kit today, hopefully this will fix the problem.

Anyone with a NBS ECSB installed shims? Pics or advice would be appreciated. What's the proper pinion angle for my setup?

Got my shim kit in today. Can someone PLEASE post up pics of the install or at least where they even go? The kit came with no instructions at all, and I can't find anything online about how to install them. Part# was 4975BLT.
