Just replaced cantilever springs and reusing the 6' board (606) and the supreme base (656). For the diving board, I found 2 different diagrams. I have attached the two diagrams. The diagram with no spacer is from April 2019 and the diagram with the spacer is from June 2011. One shows I need to use a 1" spacer schedule 40 pipe s/s and the other does not. When I took everything apart, I disposed of the old spacers which were there. My plan was to put everything back the way it was with new hardware, but now I am missing spacers as they were not included with the new cantilever spring kit I bought. A new kit with spacers is $155 online. I was wondering if I need to use these spacers? If so, does anyone know the dimensions (I.D., O.D., and length) so that I can just buy the two spacers?
