So, there is finally something more to display!
The two newest items are the head and the booster set on the rear of the Frame. The hub for the booster set actually helped with my head problem by providing a new mounting point for the head. From there I simply built on as minimally as possible.
The only part that still eludes me is the attachment I must add for the “Evolutionaries” rule mod. However, this should not be too big of an issue.
