I had no idea what brand to buy, and bought Dutchman 35 spline axles from Dr Diff based on his recommendation, and have no regrets.

According to Dr Diff they're one of the few mfrs that can be trusted to make the axle the proper length for the OE style tapered bearings which I wanted to keep. I doubt anyone else on this part of the board cares about that though, so that's where my testimonial is going to end....
