39-027E operator track

A quick learner from Midwest says:
Will the 39-520 track work with the 39-027E operator?
Thanks

Dave Sr. from SWISCO responded:
I'm afraid the 39-520 and 39-027E are not compatible. The 39-027E has a nylon bearing at the end of the arm which needs a track like the 39-533. The 39-520 track would take an operator like the 39-365 with a metal bearing at the end.
