I've been in contact with a gentleman named Larry, and he bought a full set. Try giving him a call at 201-595-8560 (office) or 201-796-8544 (home). Good luck to ya!
I did speak to a smart lady who drilled a hole in the drawer rail and she used 100# picture hanging wire to connect the hole in the rail to the rear fitting of the drawer system. Sounds like it might work real well. Again, good luck!!
