Console Auto vs 4 speed

What's the difference in the console body between the auto and the 4 speed console? I can see the difference in the plate, but I cant really tell the difference in the body. There must be though, based on ebay selling prices anyway, I would hope there is a difference.

I have 2 Auto consoles (I think are auto consoles anyway, only one has top plate) and was wondering what I would take to make 1 into a 4 speed console.
