Can confirm, I tried to size the original bolts to the new brackets and in both positions... neither
bracket-2-knuckle nor
bracket-2-caliper position fits
My local big box hardware stores report having the exact fit bolt, but likely will be in the specialty drawers with all the metric items.
I'm scouting the Home Depot near me for two pair of matching bolts that are the same as what DF provided.
When I logged the same issue in my build log it was suggested to me check a
Fastenal in my local area. there are two in Chattanooga listed.
