These didn't eat holes in the cases like the GMT800 Duramax ones would. It was the only upgrade I could find at the time. I did that, shift fork pads, and a 32 spline input/bearing so it would play nice with my 4L80 swap.

The shop had it done in a day which kinda shocked me, they did tell me they don’t see these 243cs often anymore and didn’t think that snap ring kit was available anymore. So no biggy, I have a 3 year warranty and I doubt it will have any issues with the mild abuse I’ll give it.
