Default Velcro Centaur G and Shuttle Fleet v4.8

So I'm trying to recreate some cancelled shuttle missions and wanted to better integrate Shuttle Fleet v4.8 with the Velcro Centaur G. I got the Centaur situated in the payload bay, but when I go to deploy IUS-style, the aft end rotates down while the front end remains stationary. I'm trying to get it to where the front rotates up and the aft is stationary. I played around with the attachment points in both the Centaur G config and scenario, but no joy. I included the files and a screenshot for reference. The red highlights are what I changed from the original files. Any ideas?

CentaurG.cfg

My initial guess is that the shuttle is rotating a different attachment point than you intended, probably one up by the payload area of your centaur. Or there's something up with the ROT and DIR values.

Well, my initial guesses were wrong. After testing a bit, I found it's the z axis on the Velcro3 attachment point, since as it is originally the z axis is slightly forward; what you want is the attachment point somewhere aft by the engines. -1 is somewhat close, and if I had a bit more time I would have seen if -1.5 is too far, but alas, I have some stuff to tidy.

That did it, thank you! I changed the z-axis to -9 (the length of the G Prime) and changed the z offset in the scenario to -4 and it works like a champ!
