My casement windows, 2 of them, need the inner teeth part replaced as they are stripped. I tried moving different handles from other windows but they just don't work. Is there an easy fix for this? I bought a whole houseful of windows in 2003 from an Andersen distributor. I feel if I can somehow replace the rounded teeth for the cranks, then this would most likely solve my problem. Is this even possible? The screw placements are 2 5/8 in. apart. The number I found on the casement cover is 1361530 ST or 1361529 WH. I am assuming ST is for stone and WH is for white. My windows are actually stone. Any help would be appreciated. Thank you! John
