casement window tracks needed

Good morning!

I need to locate the parts to repair a window that was installed a few years ago that did not have the tracks installed on it for the operators. The daylight on each is 18" for the glass, the casements are around 22" each which give it around a 48" outside to outside of the window. The operators are "Truth" brand with an identifying number of "30744" on the operator arm. As you can see the swinging window does not have any hardware on it to accept the roller on the end of the arm, both for the right hand and left hand as well. Please advise what parts I need in order to make the windows operable by the handles. THANK YOU!
