Dont worry about the weight of the VCR. You could probably stand
on it IF you dont jump up & down. Things were built different then. I remember
walking on the hood, trunk & roof of my '72 Olds Toronado. Four of us
sat on the roof for a good view of the fire works. No damage, just
made a popping sound when we got off.
Try some rubbing compound in a corner somewhere see if it helps.
IIRC there were other threads on the Avanti cabinets also.
