I don't know about the engine mount bracket, it is too long ago, but the rod is the same. You didn't state what year of truck you are talking about. On the 55 frame, the V8 mount holes in the front crossmember may or may not exist. ( They will not likely exist if the truck came from the factory as a 6). I had to make 2 pads and attach them to the front crossmember to fit the small block installation.
