1977 KZ1000A1 owners help...seat hook pic needed

I'm in need of a pic of anyone with a fairly original A1 to provide a decent pic or two of the seat hook....my search of the forum turned up someone last year or so looking for the same thing as both my 77's don't have a boss welded onto the frame to accept the hook and spring like my Mk2 does.

the fiche at PZilla shows a 78 frame with this 'tab' and a PN for the seat hook for the A2 but nothing listed for the A1.

I'm curious to what did the A1's come with as new???

any help is appreciated

I was thinking that the seat hook was added to the A2 in 1978.

1978 (no seat hook, but has a tab)

1978 (has a seat hook)

1978 A2 (has a seat hook)

1977 B Ltd (no seat hook)

It was probably me...my 77 kz1000 A1 did not come with one.

thanks for your time and effort here Martin, odd how the 77 model was made without it.

Also I noted on these apparently original bikes how the frame paint varied from quite satin to low gloss.

Here are a couple of pics of the helmet hook from my 77 KZ 1000a1
