Hi Trevor
Thanks for responding. I'm really struggling with this now and having spent a few hours in this I am no where nearer figuring this one out. Being an engineer this is very frustrating. Since me last post I have found another of the spring clips.
If anyone is able to remove their drawer flaps and take a photo on the inside this would be really appreciated as may give me an idea how this goes together. I think I have all the parts.
Thanks in advance
