Looking for the part number of the exhaust gasket that is located at the flange between the 2 cats on a cali emiision 2000 4Runner. Local parts store said part is unavailable. I had throw a P0420 code the other day and came here to investigate. After cleaning MAF and restting code, I found a leak in the exhaust at the flange connecting the 2 cats. The gasket appears to be cooked through. Looking to replace gasket instead of the 2 cats!

Thanks!
