Hi Pookie, this will answer all your questions on the webbing and blocks:

The cork/cloth webbing is unique and in my research, I have never seen any engineering drawings or notes on it. The original webbing was two parts. the front piece extended from the front holes in the front of the frame to about 2" beyond the front mounting hole of the cowl numbered 1. The second piece extends from that point under the splash apron to the rear of the splash apron. It was glued on with rubber cement during assembly. The block shown is a mounting block which is indexed in my article...a rubber impregnated cotton twill pad. Of the twenty I have collected, they are all calcified. They are fastened to the wood block with two #4 blue upholstery tacks. Bratton's tapes are 1/16" thick, the originals were about 1/32"...I think the cork/cloth looks like a piece of window setting material that was forced into service as a anti squeak tape.
Good luck on your restoration.
