I have the medium transport chassis available but it seems when I choose the "Space Yard ship" vechicle type it demands I use 50% of my tonnage in cargo holds.

This leaves no component slots or available tonnage for a repair bay or a space yard component.

What am I missing?

In the default rules, space yard and repair bay components don't have the "Cargo Storage" ability. To fit them onto a transport hull like that you'll have to go into the components.txt and add the "Cargo Storage" ability (recommend using 0 for the amount) to each space yard and repair bay component. Otherwise, you'll have to use a standard hull big enough to hold them.
