if you cant find it...... MAKE IT there is this wonderful stuff called gasket paper ( autobahn and supercrap auto sell it ) 10 mins with a pen and a sharp blade like a craft of hobby knife and you have what you want... best thing is you can buy better quality paper than even the gen nissan sets are made of for 1/2 the price.. the money you save you can spend on a gen head gasket if you need one... I carry about 10 sheets of gasket paper in my toolbox, and have lost count of how many cars etc that I have made a gaskets for over the years.

If its an oil seal eg side covers etc.. get the OIL paper.. if its water get the WATER paper.

the only issue is, all the young folk that work in these auto joints dont know what gasket paper even is... I buy mine from REPCO
