The damaged plinth is now repaired and refinished in a slightly stippled satin black to match the original finish and I found the type of hard feet I wanted. The other plinth will be redone to match.
As can be seen, the front is different to the HPD equiped Cheviots. Note the sagging surround. Both are like this.
Here's the removed driver. You can see the Girdacoustic radial bracing ribs are glued over the surround and right up to the back of the cone's edge. That'll be fun to detatch and refix!
Next job is removing the cone and fitting the new surround.
More photos soon.
