1929 Special Coupe top

[Ordsgt]

I have been asked by a friend to find some information in regards to the top of a 1929 Special coupe. He received a top kit and it has the grain running fore and aft on the top but the back which covers the window goes side to side. I found an old Lebron Bonny instruction that made reference to that. Most people tell me to look it up in the standards and judging manual Chapter 9. I have the manual and no where does it make reference to grain direction. Researching photos I am not able to get quality pictures that show the grain direction. If anyone could advise and provide a source for the information I would appreciate it.

Thanks
