Need help with a bolt

[Ultradog MN]

1970 4000 AP.
I did a transmission swap on this tractor.
I've done a dozen front splits and know what bolts go where.
This is only my second rear split. I did pull the hydraulic pump to measure shim clearance. I also have the right side trumpet off to address non functioning diff lock. Waiting on a part for that.
The tranny to rear end, pump, etc is all back together.
I have one special bolt left over. I don't even remember seeing it when I took things apart. It is not from the front split.
Don't think? it is from the trumpet.
5/8 head, 7/16-14 thread.
Where in the heck does it go?

Thanks Mark.
Good guess but the head on this was painted - originally blue then the yellow I sprayed it. Had to be on the outside of the tractor somewhere.

@bb56
Thanks also but no. That rear seat stud is very different.
PS,
Is your screen name a reference to battleship USS Washington - BB56?

I thought that bolt went through the housing to pin into the PTO valve.

You are right.
Thought I was looking at the diagram from the inside. There are 2 bolts on the left, outside in that location and they are both intact.
Hope someone can help me figure this out.

Is it possible it is not from this project but from some other project where you removed the PTO valve?

Thanks.
Nothing with yellow paint.

My only other thought was that someone before you had used that bolt some where it didn't belong but then you would be missing a bolt some where during assembly.

I hate it when it's all back together and you have a bolt left over.
