Advice needed on how to fabricate a plug & mold for carbon fiber layups

I want to create a carbon fiber targa top for third-gen F-bodies, but I haven't figured out how to make a quality plug and mold. Essentially I want to create a one-piece carbon fiber top with nine aluminum inserts so that it can be fastened to custom mounts that are retrofitted into the T-top channels.

I want to create a plug that would then get used in the fabrication of a two-piece mold for vacuum bagged & autoclaved carbon fiber components.

Anyone have some fabrication experience that would be willing to share some tips? I need to be able to create the molds at home. There's a shop in town that could probably evacuate the mold and autoclave the part for me, but they aren't interested in creating the mold.

Try this book:

Fiberglass & Composite Materials by Forbes Aird. It's HP Books # 1239 published by The Berkely Publishing Group.

Here's a link:Fiberglass & Composite Materials

I'd use the styrofoam plug method detailed in Chapter 12.
