These I built using a bunch of parts from various mods.  The IUS adapter is fairly simple and just uses the hollow tubes from NearFuture Exploration. Also ReStock for the forward load cradle, it is just a handful of gold RoveMates clipped together. With a fully assembled IUS it is about 30 parts, The CISS is more complex but same concept. Tubes from NFLV and for the "greebles" I used ScanSAT and SpaceDust instruments. 70 parts total with the Centaur installed!
