Terry. I generally use plywood and foam, it works pretty good. HRP

 

Webbing then 4" of foam ,2" for the backrest .

 

Lang's lists repop originals for the front seat.

 

Langs saying temporary out of stock.
Has been for about a year.

Plywood, webbing and good modern foam. Sculpt the back to fit the seat divider

 

Thanks for your replies.

Could someone give me a description or part number for the foam rubber I need? And a source.
Thank you
