We purchased quite a bit of 0.375 and 0.25 7075 hex from onlinemetals.com in 2011 and we still have at least another seasons worth left. I confirmed with a call to them that they discontinued it last year for reasons unknown to their rep.

My place of employment, Oshkosh Corp, has a supplier that will supply this flavor of shaft, but will only supply to goverment contractors. Weird.

I'll make it a personal quest to find a supplier...
