Hi all, I am trying to rebuild seats for my 59 TR3A. I actually have all new parts (frames, padding and springs from TRF and seat covers from Moss). The problem is I can't find instructions and I have nothing to refer back to. My previous seats were not original. I think they were from a Spitfire. I have found bits and pieces of information about wooden tack strips, etc., but I still have the following questions: 1) What is the purpose of the flimsy white cotton material included in the TRF padding kit. I have two small square pieces and two long rectangular pieces. 2) Is there any padding in the back of the seat (behind it) or is it just leather/vinyl over the metal frame. 3) Should the material on the back of the seat be glued there or just enclosed beneath the vinyl/leather. Thanks in advance for your answers.
