You will never find a locking differential on the front of any vehicle because of the horrendous handling that would result when turning corners. There was a 4wd truck in the '60s that offered that, (I think it might have been a Jeep Wagoneer, or something like that), but it was understood you didn't drive that very fast on the highway.
I welded up the differential on the rear of a '72 Dodge Challenger used for racing, but it had to be street legal. It launched great but I could never get it to turn without sliding the back end. That wasn't something desirable on an asphalt race track.
