I agree its not too hard to make one from the "spool" of O-ring stock--one guy came into the parts store looking for a similar o-ring on a tranny tailshaft,none available from the dealer separately,so he picked through our boxes of assorted o-rings with no luck for several minites,I was about to suggest getting a used one from a boneyard,when another counterman suggested looking up an oil filter in the Wix catolog in the numerical listings,where they give you all the measurments like thread size,overall diameter,length,--and gasket dimensions!--I found a filter that had the exact square cut o-ring on it--he bought it,peeled the o-ring off,and threw the filter in our wastebasket,since it was one that he had no use for(wouldnt fit any of his vehicles)--it saved the day for him--maybe you shall be so lucky!. /forums/images/graemlins/crazy.gif
