That reminds me, I need to order rotors and pads for the Prius for a brake job over spring break (almost a pun), in case the Corona virus screws up the supply chain. I also have a big box of titanium bits from Harbor Freight, though the current thinking is maybe that American Manufacturers should broaden the countries they source their parts from a bit.
