D8 & D9 bonnet differences

[brillo21]

Hi all

I appreciate that a D9 & D8 Bonnets are not interchangeable, but does anyone know how to tell the difference between the two without a test fit ?

I need a replacement bonnet and have found one a long distance away, but the seller does not know if its D8 or D9, is there anyway I can tell from photographs of the top and underneath, are there any distinguishing features.

Any help much appreciated

It's been a long time but I think it's as easy as D8's have two bonnet catches while D9's only have one.
