Thanks Terry.
But could you give me a hint on what word to search for,
Ive done search on your name+ Sheetmetal or your name+Floorboard and your name+measurment.
Yup you also need the steering column floor plate and its spot welded to the lip of the firewall and Bill Monzo reproduces the part www.northnbill.com. You can see it in the first picture although a little blurry in the bottom left hand corner of the cowl and I have better photos on my other computer. The other piece A is also reproduced and I will have to check my archives when I get home but I think that Bill also reproduces that part but its not on his website.
Here is a better picture and it was Bill that reproduced the part. The 3 small holes in the plate is where you face nail the part to the back of the floorboard and the 2 larger holes are for the rubber bumpers for the clutch, brake pedals and the plate is also fastened through the D nut on the right hand side of the plate.
