Yeah, ETKA doesn't know that number, and on the screen that shows the brake lines, there are no washers or bolts called out, and the rear lines clearly show the bolt captive in the end.
The part numbers are 1J0-611-763-AD and 764-AD. I only know this because I had to replace one once that some kid tried to replace a caliper on and mangled the bolt beyond and hope and I tried to buy just the bolt and couldn't.
Nice to know the aftermarket has a solution, even if it the picture it clearly looks like the bolts and washers that come packaged in aftermarket "rebuilt" caliper boxes (which we never use anyway).
