Hi thanks. Mine is the one nearer to the mid silencer, red circle below. Anyone can help with the outer diameter? 68.5mm or 77mm? Thanks

Hi my hybrid Rx400h exhaust gasket before the middle silencer needs replacement. I checked those online parts diagram and it gives me part no 17451-22070. But when searching from suppliers website 22070 keeps coming up related to diesel engine but 17451-22060 its more for the Rx400h engine. From what i gathered, 22060 has a smaller outer diameter pf 68.5 while 22070 has a larger 77mm outer. Has anyone replaced this before and can advice on which one is correct? Thanks
