Dan, you’ll want to use 1/2" x 4-1/2" Grade-5 or higher for a secure mount. They aren't included, but you can find them at any hardware store.
The mounting holes on the Demco DA75 Brake Actuator # DM33CV are standard size for bolt-on installs, and torque to spec per the included instructions, which I've also attached here for you. The torque specs for these bolts are 75 ft lbs.

Hey Dan, did you manage to get the right bolts and mount the brake actuator securely? I'm curious to know how it worked out for you, as it could help others in a similar situation.
