This has been noticed and posted by others before, but SS86 Grimlock has a fully molded interior neck piece in alt mode that is hidden by the exterior neck pieces due to, um, dubious deco changes from the renders. Removing the piece does affect transformation slightly as it provides the small square peg to plug dino head onto Grimlock's back in bot mode. Exterior neck pieces: same 'way too dark' smokey plastic as the chest window, painted over in gold. Interior neck piece: fully molded and detailed just like the G1 and MP figures, same swirly gray plastic as most of the figure. Posted earlier: This is what it would look like if they went with the clear yellow neck pieces like the renders. Custom mod shown.
