Tintype photo identification Ulysses S Grant?

[sgodschalk]

I found this full plate tintype at a local estate sale. On the back it noted that J.Garfield, R. Hayes and US. Grant were present in the photo. It says it was taken on Election day 1872 or 74 at Morris Crossroads, Pennsylvania. Of course the image was flipped, so when I scanned it, I flipped it and enlarged it at to make out the faces. I was wondering if maybe you could help me identify them as it is a low resolution photo. I believe Garfield could be far right on the balcony, but thought I would get others opinions before spouting off that I found this wonderful piece of history, to all of my friends.

Any help would so very appreciated.
