'30 side mount plate
 

attached is photo of a side mount plate; note the uneven recess. Does the side in the photo face out, so the arm bolt would fit in the recess? Also, these look different than some currently sold by the vendors.

Don't quote me in 1970 my town sedan the recess part is on the outside the nut goes in the recess area.

thanks JW; see another photo of the left side plate that shows a slight curve which I assume is the offset? The concern was that these plates are bent
I believe the studs were replaced or installed ( which we removed) that were in backwards. The raised boss on the other side should face the arm if understood correctly.
