In Need of a T-Handle Closing Plate Thingy

I need to get hold of a closing plate that is welded onto the rear valance that allows the hook on the end of the T handle to locate in it and hold it closed. I think that makes sense!!
I have been to Karrman Konnection today and they do not have any and are not planning on getting any more made.
If someone could please photograph their rear valance where the handle bracket locates and give me a rough idea of the measurements I can make a replica nad get it welded on.

Thanks in advance...
