I think you mean you mean you measured circumference rather than diameter. The diameter, outside to outside across the top, is the number you need. I don't have much experience with Fishers prior to 04, but all the GF aluminum full suspension frames that I'm familiar with take a 36.4. Not super common, but easily obtained from a Trek dealer.
Thank you so much for chiming in. It was this post below from another site that got me all confused and why I posted this up and lead to my misuse of terms. Obviously not trying to create any disharmony with this person's attempt to help.
I just measured the diameter and yes 36.4 was pretty much what I got with my ruler.
Thanks again for chiming in!

Take a piece of string or strip of paper, wrap it around your seat-tube precisely, take that string and measure its length in mm, then divide by the number pi. That is the seatpost clamp size you need.
