You have to advertise for them on the Mopar car forums in their "wanted" sections, and then hope that someone has them to sell to you.
They do not exist in the aftermarket, or reproduction places.
I rebuild lots of those calipers as a sideline business, and i have a difficult time finding them when i come across disc brake set ups when they are missing.
I was looking into getting those bolts reproduced, but the cost to do that is way to high for the average person to attempt something like that. Then there is the heat treating, hardness, charge for those bolts too.
The bolts really couldn't be made to make any type of profit on for such a limited market.
You just have to go to the local hardware store and buy yourself some 7/16 fine thread bolts.
Good luck to you anyway in your search.
