I tried to look for a sealed, double roller bearing in the 17x47x14 size for the famed "large bearing" front cover and can only find it in a single roller. Granted it's .276 bigger in overall diameter, its still a single roller bearing. Stepping back to the 17x40x14 double roller bearing is still an improvement, when trying to retrofit a '40 and newer front cover. Appreciate everyone's input and ideas these rebuilds.
