Different height passenger side engine brackets

Thanks for the pictures Oldmanmopar. Lets see if we can use yours for the question. Using the 3d picture ,the bracket in the back on the right hand side without the pad attatched, is laying on its flat surface. If I measure the height from the table to the top of the bracket right across the bolt hole I get 2 inches on one of the brackets. On the other I get close to 1 3\4. The bolt hole height also differs by 1\4 inch. Every other dimension on the two brackets is the same. Both will fit on the 340 and the k frame. I placed the motor and mounted the shortest one initially thinking it was the correct one. I then leveled the frame to the cement floor side to side and placed a level on the intake manifold with the carb off. The passenger side was low. I don't know if it is engineered to be low at rest because of lack of engine torque, or if the engine should be level. The taller bracket would bring it up closer to level. Just want to do it right since I have both size brackets.
