Did you drop the engine, K member and trans all as one with the torsion bars in the car yet?
Car body and torsion mount cross member supported "Up" as you are dropping Engine/Trans and K-member with torsion bars > dropping Down.
Then the torsion bars slid out when you dropped the K-member far enough > bending the rear torsion socket/mounts down in the process.
