64 Valiant 2 Door Sedan Carpet Questions

My 64 b-body has a few metal brackets at the toe board and the carpet slides into them.

It also had small rectangular brackets under the inner sill plates that hold the carpet down.

Not sure if these are true for same year a-body.

I hate cutting carpet, but it did cut like butter from the back with a new blade in the box cutter.

I left it long on the sides on purpose, then drove it for a while, even though it fit and conformed extremely well. It allowed the carpet to settle more.
I ended up trimming less than I would have if I cut it to fit the first time.
