Your part 39-095 rh operator, is that for a window made in 1977 or 1978?? Let me know and I will order.

The original operator for 1997 had a black nylon shoe mounted under the end of the arm. It might have #7191-2 stamped on the bottom of the operator. The 1998 operator has a stone color shoe mounted on the end of the arm. See if #7191-2 is also stamped on bottom. With that being said, I believe our replacement 39-095 operator should be a match for you. It is a newer style that yours, but I think the only difference is that the plastic cover has mounting holes going through it. The 39-095 also comes with a replacement track if you need it. Handles are extra.
