Kodak ektachrome 400x

[Rhodes]

I got 2 boxes of ektachrome 400x, val. date of 2003. The person who gave me had them store in the fridge. Do I have to, or should I compensate do to the age of the film? Also one of the rolls will be pushed, possibly to 800, I have to extend the FD to 7m or 8? I use tetenal 3 bath kit, fresh mix FD is 6:15s (or 7 for fuji films)!

PS: Did I mention that I also have kodachrome 25 and 64 120 and I am going to develop it in the right manner, using a 14 steps cycle!
