Are the 4 pot bonnets the only ones to have a cross bracing ?
Edit
Looking at images it looks like the 4 pot have cross bracing, and the V8 not. I was trying to identify my S1 bonnet, it came with cross bracing, so I am assuming it is 4 pot.
I fitted it to my S2 V8.
It wasn't easy, but I did not consider the differences when I bought it, and then having spent ages stripping it of paint, it was going to go on come hell or high water. I retained the S2 slam panel.
