As long as you respect those limits and >don't have an O200 crank, you're likely safe, Wolf! Wolf! Wolf! Wolf! I take it all back. McCauley explicitly limits the C85-1A/B90 combo to lengths between 68.5" and 71". No one in the FAA in their right mind would issue a field approval, much less an STC, that doesn't meet those limits. Like I said before, get it cut down or replace it. I've seen too many C85's with broken center main bearing webs and/or broken crankshafts to risk chancing it. My own, uneducated opinion is that the lower limit is of more concern than the upper limit...
