Truth crank operator

Question

I have an old Truth operator 45251. It looks like this could work as a replacement.
Product Code: 39-325
X-Drive Split Arm ROTO Operator, Vinyl App
The only dimension I do not have is the length of the casing. Also, my windows are wood, not vinyl. Does that matter

Thanks for posting. Based on the end of the link arm, I think you actually need something like the 39-171 and 39-172 Dyad Operators. Please compare. Review the dimensions and see if you think this matches what you seek.
