Marty,

I did it about three years ago. If you remember how you took it apart, you can get it back together without too much cussing. If you do not remember, you most likely will need to see photos and/or have someone talk you through it.

Jim Carter supposedly sells a good installation kit (has more parts than other vendors supply). You might need to obtain whiskers for the vertical stainless steel bar (see link in thread below).

It helps to have a helper.

After you get it done, check with me about a custom sliding-window stop.
