DynaTech motor mounts

Has anyone tried these small block lock up motor mounts? The passenger side is just a cheap parts store replacement and the driver side looks like the same thing with a couple of flat head cap screws countersunk into the thin metal bracket. For $140 plus shipping I was expecting more, I have a couple of O'Reilly power torque motor mounts and they look identical. The nuts are even welded on crooked just like the parts store ones, I'm afraid that when the weight of the engine is on them the two flat head cap screws are going to be resting on my cross member
