I purchased the leather from a local saddle shop. It was referred to as "sole leather" because it is relatively thick, about 1/8". It was very stiff but leather can be formed easily by soaking it in water for a few minutes.

It is attached to the bottom of the ash block with a couple of small screws but the bungees keep it held in place.

Round headed rivets per the original plans instead of threaded fasteners in this location would most likely eliminate the need for the leather cuff.
