Hi guys,
Don't mean to bring up this old post unnecessarily but I actually came across these pods last week and love them. I had the problem with the pod rockets having their thrustVector really off. So I opened them up in blender and fixed the incorrect angle. I also made a cargo variant with KIS that has no Kerbals, a probe module and KIS Inventory. This is basically like the dragon cargo variant. I also changed the textures so the windows are not glass, they are the hull colour, looks kinda cool.
Not sure what the rules area as I know this is someone else's work but I fixed the problem I see a few people have had and would be great if people could use these pods again... maybe its worth me sharing the files?
EDIT: This is in the latest version of KSP BTW
