Dimensions of saddle bracket ?

Hi, I was hoping to carry out a modification to my Delta this winter but need the dimensions of the saddle bracket fitted above the door that locates the central roof bar.

I took these dimensions at our last camp but unfortunately have mislaid them. Since then I have had a shoulder op. and cannot erect my Delta for the forseeable future.

If anyone can supply me with these dimensions I would be most grateful. Just the hole centres would be enough.

Many thanks,
Phil.

My discovery is up in the back garden at the moment, 60mm between centres, width of "bottom" bend 32mm. top 20mm.
Hope this helps

Thats great thanks very much.
Happy camping.
