support bars

[Meirschwartz]

Hello guys.
Over the weekend, I removed the support bars and the pan cover, in order to service the transmission.
I put aside the 2 nuts and 2 bolts of the pan, and started removing the other nuts of the support bars. When I wanted to put every thing back I found I have 2 nuts that are a little bit smaller in their external diameter then the others.
Can you tell where they suppose to go?
I market each one in a circle with a different color.




thanks.
