Hy panmanhd, if you remove the piece that the yoke went into you should find the seal and felt inside that, the p/ns for the seal and felt are
National 411330N for the seal $6.90 Can. at RockAuto
National 5M89 for the felt $7.47 Can. at RockAuto
sorry I couldn't find a FelPro p/n for the gasket, hope that helps.
