Someone else told me the same thing. I'll have to take a look underneath my neighbors RX300. Not sure if is an M5. I do know you can take that bolt out and go to Home Depot and a lot of hardware stores and they have something there you can screw the bolt into various holes until you get the one that fits.

dont want to take the chance to unscrew looks really rusty and i only can hold one nut on it. if anything i probably just go grab whatever would fit to it in metric.

thanks for the help
