The BSA sash I would like to replace has a metal channel 13 5/8 inch in length and 9/16 inch wide. Plastic end pieces have white plastic wings that are 1/2" wide and keep the whole thing in the window channel. Wings are partly broken off. Pully ropes also broken. Can you sell me a new piece complete that will work? I so please provide cost and part number and any ordering instructions.
Thanks Bill
