I think they're supremely uncomfortable cars from a climate control perspective. The AC is underpowered and the miniscule windows offer very little airflow. The car acts like a greenhouse very effectively.
My father picked one up from the widow of a collector back in the early 2000's. I've had occasion to drive it a couple of times. It's a fun car to drive for the comments you receive and little else. It sounds like this EV conversion would help with the underpowered performance, but I don't see how they could fix the terrible environmentals.
I think I have bad news for you... On the product page they mention "heating" but nothing about A/C. That will typically necessitate an electric compressor and associated plumbing, which is removed when the engine is removed. So I think this conversion is sans any A/C unfortunately.
Luckily there will be no more big engine that heats up everything around it. That might help a bit.
I feel like that would be next on the list anyways because the original AC system was belt driven off the motor that no longer exists. And since this sits in place of the original motor I would imagine if there isn't already some special motor to drive an accessory belt then the AC was removed anyways. Maybe fitting a new AC system was already considered but otherwise there likely is none.
