There is no special tool. If you're unable to detach the operator arm from the bracket, try unscrewing the bracket from the sash. It looks like you can get at it from the side.

Oh, I see. Sorry for the confusion. I thought you meant you were having trouble removing it from the sash, not the sill. The only way to get at those screws is to remove the sill cover. As for the operator itself, our 39-171 and 39-172 appear to be good matches, assuming the dimensions match up.
Removing vinyl sill covers can be tricky. Looking at your first photo you sent, it looks like there is a seam on the bottom of the sill cover. That mean it might be one that snaps in place. Take a small screw driver or chisel and try to pry it up at one end and see if you have any luck. You just have to be more careful that you don't crack or damage the plastic on the frame. If you are not comfortable doing this then I recommend hiring a handy person to come out and do it for you. |

Ah, perfect. I agree, the 39-325 appears to be a great match.
