D series blade fit my GT14?

[glgrumpy 35]

Found a nice big blade from D180 I think for sale. Has the bigger frame and the turn lever looks farther out onthe frame than others. In past I bought a blade and it is ON the tractor, but is actually not long enough frame. Think it was a short frame unit, even with54" blade. This new one also has 54" blade and looks some taller on same blade. Comes with the mount for axle. My mount went on, but was a hair narrow for bolt line-up, so thinking 200 might be wider? What ya think?
