Measure the size and find a bolt store locally, look for grade 8 bolts and nuts and some locktite. Feel lucky also, someone may have been trying to snake your CAT and got interrupted. You can probably get away with using some grade 5 bolts more commonly found at Home Depot of Lowes until you can get replacements. Its probably easier to do it yourself even if you ordered OEM bolts from Toyota. Definitly going to pay a mechanic way to much to do it.
