We were lucky to have such a large amount of space to work with ........ the pics will show you the depth of the bulkhead behind the doors and how tall we were able to make our attachment brackets .......... don't know if you'll have that luxury. John
John,
I appreciate the great explanation. I don't have the depth you did, but you've given me an idea - I may be able to cut a ~3/8" thick ring the size of my box, glue that to the luan plywood, then upholster that as you describe using screws to mount the box from behind. Headed out to the shop to play a little. Thanks!
