E36 trailing arm brackets bolt up into a pocket in the BMW 3-series body. Recommended torque is 57 ft lbs.

Backdraft brackets are custom, essentially flipped over and bolted down onto the frame with 18 ft lbs of torque each. Completely different stresses and load from OEM BMW mounting. Perhaps prior alignment shop saw E36 on my car and went to 57 ft lbs. Gussets on older builds seem like a must... and go for new bolts while in there.
