700R4 crossmember location

[Arvizu9618]

I know the CM will have to be moved back, but my question is

Do the wholes already exist in the frame?

I have several factory holes on each side, but are the correct one's for the 700R4 already there from the factory???

depends on the length of the tail shaft. my 700r4 has a 6" tail shaft so i didn't have to drill any extra holes in the frame. but the cm should end out in the holes that already drilled in the frame.

I had the DS shortened 3".
