I need to replace the Head(cam) Cover gasket (F20110235D) and have found a nr. of alternative manufacture part nrs. (including Ford) which can be easily accessed in UK and to be on the safe side, need to obtain the Intake manifold gasket (FEMJ13135) when I have to remove/split this manifold, but having done the 'google' search cannot find any alternative nr's for this one !

Can anyone give me any other manufacture nr's. (or recommended web sites) so that I don't have to order from Mazda UK ?
Mny thks for any help.
note: plenty of 2.5 diesel gaskets ( and V6's) but no good for the 2.0 petrol models.
