I had trouble latching the cowl on 9366K, after reassembly. After several hours of frustration, I discovered that half of the cowl latches were 3" long and the other half 3 1/4" long. I went to the Univair catalog to see what went where, but the catalog has just cowl latches, and no option as to different sizes. After considerable experimentation, I discovered that the short ones fit best on the right and the long ones fit best on the left. Has anyone else had this experience, and if it's standard, why does Univair offer only one part number?
