I'm glad I insisted on the picture, it's completely different in the mounting than I thought it was. In this case, you can try and put some shims behind the servo where it bolts to the block, but make sure it goes all the way across the mounting tab behind it. Wouldn't want you to break the new servos.
As Graham stated, it may be fine for normal flight (hovering, and FF). If you are trying to get into some Smack, then I hate to say it, but I would rekit everything into an Align frame. But, you "should" be fine the way it is. I'm not sure of a way to correct this issue 100%.
