Has anyone updated a monitor heater? Do the vent holes align?

[catamount]

I'm considering replacing my Monitor 41 with an updated Monitor 441 (I really want to be able to program the heater and the 41 doesn't provide a way).

What I'm wondering is if Monitor had enough foresight to align the vent holes between older and newer models?

That is, if I get a new monitor heater, will it be "plug and play" or will I be stuck filling the old exhaust hole and drilling a new one?

all monitors have the same opening so retrofitting a new one in and old install is a piece of cake.

Thank you sir!
