hi bonzo im still bit confused because in the book i have it shows in the picture from the face of the box section inside to the 26dia tube it says 287mm like you said and 315mm from the begining of the plate to the inner face of the box section and the wrighting below says 257mm x 325mm so its already giving me that 10mm so from what i understand thats the 10mm that i must weld the box section in
