Interesting, I'm going to measure my 200 series shaft and report back when I get home from work in a few days!
I apologize for taking a bit to confirm this but I just checked and the 200 series shaft is almost a foot longer than then 80 shaft. It does look beefier and the flanges (what looks like) the same bolt pattern. They are all about 2.5 inches between holes. The 80 shaft is 3'2" and the 200 shaft is 4' 3/8". If the 80 stuff no longer becomes available, you could get it shortened to work.
