I've had no problems using either the straight or flared interstages when building Thor or Atlas crafts. Note that both interstages connect to the engine mount rather than to the bottom of the A or B/D tanks so you need to remember to include that.

As I said in a reply just above your post... Sigh.

Copy the URL from the first post into your browser's location bar, add "media fire . com" (without the spaces) after the "http://www." bit.

Have a look at Modular Fuel Tanks, it should provide what you are asking about.

Apart from the missing nozzle on the RD-191V, it works fine for me in 0.90 running on 64bit Linux.

An excellent video of the MIR-2 (1993) project constructed in RSS with lots of KOSMOS SSPP parts:

Present and still using everything, now under Linux for 32 extra bits.

All the parts that you list are from non-KOSMOS mods, namely KSO, HullCam and the ISS Community Project (and probably Lazor's Robot Arm), not sure what this would have to do with KOSMOS? Are you trying to load a specific craft file from some mod?

No, just move the "DeadlyReentry" folder in the archive, directly into your GameData folder.
