How much of that do you get for $450?

I think I paid around $800 for a steel housing with axles and bearings from Moser about 10 years ago, ready to bolt in... just add brakes and center section.

tough to tell, but I believe you get the side tubes and the upper bracket with the Mickey ears. Their center cases look to be another $350 and up. This is still not released yet. I found a different application kit they had which was the center and tubes (basic tubes and no upper bracket) for $630.
