I recently bought a set for a stock length B-body Dana 60 so they are basically a stock replacement. This is a street/show car and not a race car. I couldn't tell who made them, they looked like a Chinese knockoff. The splines are much longer than they need to be probably because they blank out a common larger length axle and cut it per application. So far I have no issues but had I known I just would have paid more for the name brand axles(Moser, Strange).
