Cobra 8.8 differential rebuild shop question

Any more info on this? I am currently doing pretty much the same install except for 3.73s. I am having a little trouble deciding on carrier shims and looking at gear patterns. If this would be better suited in a different discussion please point me in the right direction

I've opted out of making the spreader, so far I've had decent luck with getting it in and out with using a prybar, I know that sounds barbaric but i promise I'm using it in a safe way without damaging anything. The one thing that a spreader will allow you is to get your preload correct if you do not have the factory shims. That's not to say that you definitely should NOT make the spreader, just that I have had good luck without. I'm currently onto my final assembly after taking my T2 out fortyeleven times. One thing I will add that if you opt out of spreading you will need to be careful getting your shims installed, you will need to beat them in with some form of hammer and the steel shim will tear away at the aluminum. What I have been doing is building the same thickness shim with one of the kits that include a wide variety of thin shims, dropping in the thinnest ones first and then using my mallet on the .100 shim. Sestemybe I encourage you to try it yourself. It really isn't that difficult as long as you are okay with a lot of math and trial and error.
