oil strainer/pickup gasket

Hi. I am in trouble. I am trying to rebuild my 3s ge engine and cant find where I put the oil strainer (or pickup) gasket that seals it when attached to the block. I can see from the inprint it seems identical to the water pump metal gasket. But I am not sure. In fact I dont even know if its metal, or if their is actually more than one. I saw a diagram of the TRD parts list that indicates what seems to be about 3 of them. I contacted the local toyota dealers, they say it will be 4 weeks before they can get one. Can anyone help as to what they suggest I do if I cant get one, or have a gasket? I suspect the seal needs to be spot on or it will suck air and not be prettty to the oil pressure
thanks

When I rebuilt my 3SGE I used aviation form-a-gasket by permatex as the gasket. Worked fine for me.

thanks guys for your replies. sadly i didnt come back into hte forum to check your responses. I also didnt get an email notice that your responses were given. As it turns out I found the gasket and reused it. thanks for your input
