CW will not postpone your sale date until about 2 weeks prior to it no matter how much information you send them. We have a sale date of 6/9 and in the middle of a mod right now and I got the same answer.
Also, I would go ahead and send everything in to
CW again and keep records even though you are going through NACA. It doesn't hurt especially with
CW because the left hand rarely knows what the right hand is doing. I've come to the conclusion that it is better to overwhelm them with the same info than have your mod caught up in "we don't have (insert doc here)." Trust me, it will save you lots of headaches! Good luck!
