end piece for push-up window

Hi,

Picture 1 shows the bottom square piece needed (with the hole in the middle)
Picture 2 and 3 show how this piece is missing.
Picture 4 and 5 show the hook I bought from you a while back for this same window.

I know the kit may come with more than just the square piece, i will buy the kit if needs be.
I need at least 6 square pieces (or kits).

Thanks for your help.

I have to give it to you.
What you think I need is what I do need.
Experience pays off, heh?
Thanks,
-Danny
