Will a 240Z dash fit in a 280Z?

I asked a similiar question earlier but now am thinking that a 240Z dash might become available or a 280Z dash. My 280Z dash is evidently not there. I looked under my dash cap to see how bad it was and was shicked to find there WAS NO DASH! It looks like someone has sawed out the top of the dash and then covered with a cap. At least I have easy access to my dash lights now. I want to keep my options open. Will a 240Z dash fit on a '75 280Z? Complications?
