You could use a movfr though if you wanted, it'd just be more work. The movfe should be a much more direct swap.

I did two mods where we replaced hd-85 harmonic operators on tac20s with movfr's. We retained the TK clutch and doors on that job. Instead of a connecting link from the end of the drive arm to the clutch we ordered connecting links with a bracket on the end with slots for two bolts. Took a roughly 18x24 inch piece of 11 gauge sheet steel and a ton of self tappers with lock washers and loctite to secure that plate to the raise ribs on the car door and bolted the connecting link to it. It's been years and no issues.
