i hav a 99 cobra and are wanting to do an eaton swap so the power would be about 470hp 420tq. would building my rear end with a 31 spline trac lok and 31 spline axles both out of a 04 cobra be sufficient for that ideal power??? also is the 99 differential housing the same/weaker than the 03/04 housing???
