Personally I have used Vallejo Model Air 50 Light Grey for my Huey interiors.  Looks ok to me.  According to the ultimate paint conversion chart (http://www.paint4models.com/) it apparently matches Tamiya's XF19 Sky Grey.

Any medium grey will do, the color changed due to paint batches, fading, etc.  I usually use a spray can of primer grey from Wal-Mart or the likes for the interior grey color.

So long ago and so much forgotten. I do not recall the inside color very well but I am leaning closer to that AS-2. I have some slide scans but they do not show much inside aside from an M60 with a Schlitz can spot welded to the side. One I have looking forward toward the back of the pilots seat shows the back of the seat very close to the OD color of the outside.
