Use the gasket on the rear. To properly install the paper gasket you must first soak it in water then fit it over the studs otherwise you will rip it. Another tip is to apply a thin coating of Aviation Form-a-Gasket ( this is the brush on stuff, it is not any form of silicone) to the housing gasket surface first, then apply the soaked paper gasket. Next apply a thin coating of the Aviation Form-A-Gasket on the carrier gasket surface. This will make a leak free barrier and allow the paper gasket to be easily removed in one piece ( no scraping ) if you ever remove the carrier again ( much easier and less work than RTV scraping ).
