I'd think twice about Moser axles. Here is what happens to 40 spline Moser's at Bonneville...
Note: BIG problem with some aftermarket axles is not only material science but machine science. Moser uses a "single point cut" in their after market axle splines. That is a major weakness in axle manufacturing. As is having the root outer diameter of the spline itself smaller than the main axle shaft diameter.
Also...I would not even consider "c-clip" eliminators in a performance application that would see Bonneville. I would have the housing built with aftermarket bearing ends like that utilized in a tapered or roller ball bearing (read: cartridge type or bearing and race.) Also... read that as a safety factor...
The weld on bearing end type, offer excellent axle retention and some even offer less drag with higher load capacity. Common modifications use "Ford" big or small bearing housing ends as well as a slew of others. The choice really comes down to critical bearing speed. Not to mention that you will have less axle bearing 'end play'... which is critical with disk brake applications.
EXAMPLE of what I am referring to:
