Truth 40056

Hello there. We have come across the operators with 11" or 11-1/2" Straight Arms before, and unfortunately an exact replacement is not available. Your best bet I think would be to use the 39-027E and 39-028E (or the more operators with the 9-1/2" long arms. If you can't install it as is, you may need to reposition the track that the roller slides into to make up the difference. The window might not open quite as far, but if you an reposition the track I think this solution could work for you.
