Need Help Hybrids and CVD's

Ok I just got done building my FLM Maxx today. Flm Chassis, Hybrid diffs w/the diffs FLM supplies, Flm shock towers. Rpm front arms and true track in the back.

I bought some Traxxas CVDS and the Revo extended cups. About 10 minutes into the run SNAP!!!!!!!!! The drive cup Snapped in half and broke the cvd.

I can not put my Stock axles on. Because after shimming the diffs up the one side the Stub axle supplied with the kit is not long enough. I would not be able to get the Pin screw through the stub. Its off by half a hole.

So what are my options now?
