The International Cessna^® 170 Association

my old main spring measured .323 no paint, my new spring from spruce measured .312 with the paint that comes on it from spruce. Was the spring that I had on not a 170 spring? it was on when I bought the plane. Thanks russ

Maybe it was a Bird-dog tailspring? Who's got one on their 170 that they can measure? I seem to recall seeing the dimensional difference spelled out somewhere,it woulda been here or on the old yahoo site if I did see it....
