The Fordwood diagram gives a basic wood installation. Volume 5 of the MAFCA series on "How to Restore Your Model A" has a good run down on all the pieces. This link is to a previous question of the same nature.

The B Terry Restoration web site illustrates a Business Coupe top that is similar except for the port hole & no landau bars. I hope you have your rear bow braces, landau bar bits, and the belt rail metal molding. The molding is near impossible to find and the repro landau bars aren't made like the originals. A fellow used to fabricate the belt molding but the one I've seen didn't quite look like the original in shape.
