We now offer replacement oil pump gaskets. For some strange reason, these are not offered separately or included in ANY gasket sets from any of the major gasket suppliers such as Fel-pro, Victor, Rol, etc, and they are nearly impossible to find. Many of the gasket companies list "Oil Pump Gasket" in their catalogs, but under the description, the part is listed as an "o-ring", so it is actually the standard rubber o-ring which fits around the drive area of the pump, not the gasket. So, we've sourced these hard to find gaskets and now offer them for sale separately. Another "pain in the butt" big block Mopar problem made simple and inexpensive by 440 Source!
