Thank you for your patience in this matter. Unfortunately, we have been unable to find an exact replacement for this operator. The only solution I can think of is using an operator like our 39-365 along with a new track like our 39-504 or 39-512. I can't guarantee that this will work, but it's the best solution we have.
