I have these bulks and diffs. I found install very easy, and quality very good. I was forced to cut the input shaft on each diff. I have the G4 chassis, and that keeps the driveshafts parallel, so they were too long. The HB cups work fine as well. I found no need to shim the diffs in the hybrid bulks, but did need to shim the input shaft, and capture it with the cup to keep it from pushing in against the diff cup. I found some alum. diff cups from innovative (in the UK), haven't installed them yet. I am running 5k front and 3k rear based upon suggestions on this forum.
