ANOTHER carpet install question

The further ahead the better. As long as it tucks nicely under the rear seat. I have never been happy with aftermarket shaped carpet. It always seems to be curved inaccurately. And I have installed a few incorrectly myself. Too short up the front. The heel pad is the defining factor. I think it should run forward basically until it is almost at the upward curve. Slightly away. Somebody will have a pic.
