These mats will soon be avialable from JustMatz. I am getting a set made up and once I have them I will post photos for everyone to see. You will then be able to order them direct, I will post details including price when I have them.
JustMatz now have the templates for the both 172 model (this if for 2 front mats and one combined rear). They still need templates for 16v and Williams models. So if you want thenm, someone will need to create and send templates for the mats. If you are prepared to create templates for these cars then PM me!
