Hello guys, I've just acquired 6 sets of Deluxe Innovations Maxi-IV well sets, 4 of them for Pacer/Bran and 2 for TTX. What are the two extra parts that come in the clear little plastic baggy? Tried to figure it out on my own but I don't see any place they should go or even what they are? Photo below of parts in question. Also, they come with etched metal railings that are un-painted, and I also want to patch these into DTTX to bring them into the present day. Does anyone know what brand/color paint would be sufficient to get a close match? I plan to weather these and fade the paint before I patch them over, so an exact blue match is not necessary since Id like the patches to stand out anyways. Ive just never seen a Pacer blue in model paints? Thanks in advance!
