I would really push the seller to find the head units. They’re a very distinctive thing to lose, and near impossible to sell separately, so they must have them somewhere. It would be a real shame to break up a pair of anniversary 8Ks as they were not an ordinary item, very special.

Alternatively, see if anyone else who is into Meridian gear would take them off you as-is and have Meridian make up matching head units. They might be worth it to a collector. Maybe Meridian themselves might have them back(?).

What I mean is, they’re special, so try all alternatives before breaking them up for parts.
