Casement window parts

Question

I have 8 of these old porch metal casement windows, 4 left and 4 right I need to replace. They are stamped with the name Fenestra on them. I thought I found them on your site except for the one hole I can not verify due to your picture orientation. You will see in my picture the dimensions seem to be ok other wise, i think. its the the side with the two holes i needed verified. I will attach 3 pictures or email them separately if attaching them does not work.
Thanks
Mike

You did not give the hole placements on your operator, and I also do not know which of our parts you are referring to. You do say it is a Fenestra operator. I checked the hole centers on our 39-344 and 39-358 operators. The outer holes are 4-1/4", center to center, and the rear mounting hole centers are 3-3/8" and have a #10-24 thread. I hope this is helpful.
