SB Motor Stands in right place?

[FL71C10]

I am finally starting to work on my truck. It's a small block automatic truck that I bought with no motor or transmission. The PO told me he had a small block with a 700r4 transmission in it. I have a mid 70's 350 with a TH350 out of an impala. I was looking at the engine stands and they look strange. they seem too far back and the hole in them looks like it's been hogged out. I know I may have to move the crossmember to put in the TH350, but want to make sure averything else is ok. Can someone tell me if they look ok, and if they are in the right place? I am attaching pictures.
