Do you know if all cross members (big block/small block) are the same for 68-70 B-body?

As far as I know BB, SB is the same, the difference is with auto verses std transmissions. 4 speed uses a different crossmember than automatic cars, not sure on std 3 speeds. 70 all cars (std/auto) use same as 68/69 auto cars (there may be a difference in the size of the holes for the four bolts that bolt it to the torsion bar crossmember.

The HP cars use the larger bolts, not sure about the other big blocks.
