ULTIMATE SHUTTLE IVA FULL Retro Mr. Glass What is the Ultimate Shuttle IVA? Welp as its name implies, its truly in my opinion and those of others the best IVA that's been made thus far for the Mk 3 Cockpit, ie, the stock Shuttle Cockpit.  The reason being is that these two IVA's, Full RETRO and Mr. Glass, combine the best bits, bobs, and feels of the best Mk 3 IVA's that have been made to date, creating two distinct, but very useful and very good looking IVA's.
