Will the crf 150 seat fit on a Honda CR85?

Here is why? Seat Concepts makes a seat for the 150 but not the 85. I was told back in the day that the 150's were based on the CRn85 frame, so I thinking maybe the seats would swap. I emailed Seat Concepts a couple days ago but haven't gotten an answer so I'm going to plan B. My CR has the 250F engine in it.

. I might have asked the wrong question. I looked again at Seat Concepts and see they only make a  seat cover for the R. The comfort seat is for the 150F. So again: Would it fit or could it be made to fit.
