Seat belt interchange W126

[MS Fowler]

I am swapping interior parts from a '91 W126 into my '82 W126 SD. The shoulder harness in the B pillar carries a warning not to install in another vehicle. My guess is that my '82 has not circuitry for the pretensioners.
Am I correct that I should NOT swap them over?

pretensioners became standard on all 85 and newer benzes

OK, so will the inertia part of the shoulder belt from the '91 still function still function as the inertia belt from '82? I understand i will not have the benefit of the later pretensioners, but without the circuitry will it be as safe as the original '82 belt?
