Google will find you anything! BTW - only 'Mods' are not allowed to 'advertise' Companies - we can point to Suppliers etc and say good things about them. But we are not allowed to tell when we get bad service !
ital sump gasket is deffo not the same as marina, I know because I bought marina thinking it would be the same and it isn't.
Ital is A+ and marina is A series. Any good motor factor can order these because all good gasket suppliers still list it. Not off the shelf but should be next day.
Sump gasket should be the same - the block shape never changed. Timing case gaskets are easily available - and v inexpensive, so don't let that put you off!
