Wood shims under rear motor mounts

Hey All!
I am working on a 1916 touring car and I have heard there should be wood shims under the rear mounts. Is this correct? If it is could someone shot a picture so I can see? I don't have any other Model Ts near me.
Thanks,

Here's a picture of where the blocks go & their orientation

Frank's picture shows where they are to be placed, however, that is just the start of placement. They actually go flat with the frame and between the crankcase ear and the frame with a long bolt through the hole. The bolt has a hole in the end for a castle nut with cotter pin. Place the bolt through from the outside of the frame to the inside of the ear between the ear and the hogs head. To install the nut, I like to place some masking tape in the wrench to hold the nut tight in the wrench with the threads in the nut toward the ear. Then thread the bolt from the head into the bolt. Do not snug the bolt. It should be just tightened down to the point you can get the cotter pin in place and bend enough so the pin will not fall out but is easy to get out next time you pull the engine. The bolt through the top of the frame should be tight with the nut up.

The inside corners of the motor mount arm should not be allowed to contact the inboard edge of the frame rail flange. This can cause the normal slight movement of the parts to wear small notches in the edge of the frame flange, which can lead to a cracked frame. Correct installation of the wood blocks will usually prevent any contact here. 1/16 to 3/32" of clearance is probably enough.

Blocks, not shims. The angled cutout in the block on the right side, is for the fuel line to pass through from the fuel tank to the carburetor on T’s with under seat fuel tanks. Jim Patrick

I wonder if the original post referring to shims is not about a thin piece of timber between the pan ear and the top of the frame rail? If this is the case, it is not usual practice. However, I have used 1/4" insertion rubber in the same place as a vibration dampener.
