yukon axles Any good???

I was looking through ebay and stumbled across a guy selling new yukon axles for a bodies. First off I was wondering if yukon axles are any good. I won't be putting that much horsepower down(500 to the flywheel est) but I wanted to make sure I don't have a problem. Second question is I have the stock drum brakes on my 71 duster, I don't want to switch out to b or e body brakes. I know I'll have to have the drum drilled for the larger bolt pattern but I had read on other posts that if you order Moser axles you have to tell them that you are using the a body brakes so they machine the axle correctly. I don't want to buy these yukon axles then learn that my brakes won't work. Thanks again for any input.
