Which way does this trans cross member go?

[mw67rs]

I am preparing to reinstall my engine and transmission in a 77 K10 with 350 small block and turbo 350 transmission. I took a bunch of picture as I was taking it apart so I would know how it goes back together but as usual I didn't take enough. I have attempted to attach a photo of the cross member. We will see if it works. But one side of the cross member has an oblonged hole and the other side has a dent in the cross member I assume to make clearance for something. Can anyone tell me which way this is to be installed? Does the oblonged hole go on the DS or the PS?

Thanks for the help.
