Shackle end plates question
 

First, I am a model A person and don't know much about model T's. I bought these shackles thinking they were for a model A, but they are slightly smaller than those used on a model A, including the holes. I am attaching a couple pictures of the shackles. 6 of the 8 have a Ford script on them, as you can see in the pictures, so I am pretty sure that are probably for a model T. The length of each is 2 1/2", the width is 7/8" and the holes are 3/8" in diameter. I want to sell them to someone that can use them. If some model T person would kindly identify the shackles I would appreciate it.
Thanks for any help
