Hey here's the Truth cranks I have. They're off a Marvin window from many years ago.
Looks like your product 39-317 and 318 are same - except my 4" arms have a slight dogleg bend in them.

Thanks for reaching out to us. You're 100% right, that offset bend in the arm is going to be an important factor. The only product we sell that may replace that is our 39-171 and 39-172, but my concern there is that the offset might be too big. Look it over and see what you think.
