Can you PM me the ID plate details off the donor?

If it was me i'd use Saffron, Orchid or Aquamarine if you want a HQ Sandman colour. Suburst is nice too.

To remove the side panels, just cut through the quarter below the join, right through the inner and outer, and cut the roof above the drip rail. This will allow you to keep the whole lot, ribs included and easily store them until you are ready.
