I upgraded the motor mounts from the early style "stud-type" to the later style "ear-type." My problem now is I don't have the bolts that go through the "ears" of the engine mounts to attach them to the frame mounts. At the moment. I'm just using some long bolts I had lying around to support the engine until I can get the proper bolts. The car isn't drivable yet, so these bolts will do while I get everything buttoned up.

Here's the main question. What is the proper bolt size for these later style mounts? The temporary bolts are to thin to be used long term, and I sure as hell don't want to be snapping motor mount bolts when I stand on the throttle.

You won't. The engine has nowhere near the torque required to shear a grade 5 bolt. Get the proper washer head dog point bolts from your Mustang dealer.
