Yeah, I know! it's a little insane at this point, but as they say, 1600 ounces counts for 100 lbs.
These harmless and seldom seen interior trim pieces collectively put on an additional 6-1/2 lbs on a early B-body car, so they'll have to go for a special bath as well.
No structural issues here, just keeping the headliner up and in place. I'll be happy with half that weight when they come back.
