don't try to patch this. go get a replacement knuckle and be done with it! as a bonus, the junkyard will still have the bolts for your caliper in it! (be sure to clean the threads and install new BLUE locktite on the threads. or get new bolts from the dealer with thread locker already installed.

I agree with the above. With the Original Bolts the unthreaded part of the Bolt allows for alignment in the hole on the Caliper.
If a through bolt and washer move around they will not stay tight.
Another issue is the If you use a Washer it needs to be a hardend one also and as an example a Grade 8 washer is thicker thatn the regular ones; and where would you find Metric one.
Clearly the Original poster does not want to take the Car someplace to have it fixed.
A Heilcoil would work but the PO buggered the hole drilling out the Bolt. I would not expect good luck with him/her drilling a hole for a Heilcoil.
