Rear Seat cross tube and lap belt installation

[cubflyer2]

I am restoring a 1946 J3 Cub and am looking for information and photos on how the rear seat sling, cross tubes and lap seat belt is all attached. I saw on one of the posts on restoration that the cross lower rear cross tube has two holes drilled thru the tube on both ends. Can any one tell me the size and location of these holes also how is the seat belt attach to this tube, and how is the cross tube attach to the lower fuselage cross tube. Hope someone can help with information and photos.

Thanks very much
