Bill, those USED axels on ebay are certainly no deal at the price hes asking, unless your building a numbers matching car.

Try Moser or Strange. When I bought mine from Moser, I believe they were about $275.00. And they were rated for way more than my 535 hp/560 ft lb motor would ever put tp them.

I believe there are a couple of other mfgs that offer the too, but these two are the first ones that poped into my head.
