Removing Drive shaft loop cross member - 1972 C10

[Slam'ed 72]

Getting to the final stages of the Porterbuilt dropmember rear install and I am not sure about removing the drive shaft loop cross member?

Going to cut a small arc in the back of the cab for drive shaft clearance and need to remove this cross member.

Will removing this cross member cause the frame to become weak or twist?

Thanks.........
