I see hot it works over there! An hour test is ridiculous! There must be a lot of places that have that expensive rolling road dyno to handle all the tests! Driving the car on the road and waiting for it to acquire satellites would drag it out further and expose them to liability in the event of an accident (well, maybe not - they are the government!).
Depending on where you live, your old Europa may not be tested at all. I'm not clear on all the details, but a lot of the testing was related to emissions and was done through the OBD port rather than tailpipe sniffers, etc. Since we don't have one, they pretty much forget about us. I'm pretty sure they check lights, brakes, etc. manually on the rest of the cars but I guess there are so few cars on the road that are pre-OBD they don't worry about even that for our cars. It almost wouldn't matter because the guy performing the test is probably wearing boots and wouldn't be able to drive the car in the first place!
Now in some states, they don't do inspections at all regardless of the age of the vehicle. That makes a lot of sense to me. I think the inspection regime is just another way to tax us as I doubt there are a statistically insignificant number of cars that could not pass the emissions or "safety" tests they perform now. The times I've been caught, there would be a CEL code that was unrelated to emissions or safety but that had to be cleared for 30 days before they could do a good scan.
Before they changed the law, I had to have my Europa inspected and one of the things they checked for was exhaust leaks. My the secondary tubes were slip fit into the exhaust pipe so they leaked there. Well, that failed me! I tried to explain that the "leak" was behind the cabin and in any event, it was only about two feet in front of a BIGGER "leak" - the tailpipe, but to no avail. I had to get some high temp silicone goo and hose clamps to seal the "leak".
Good luck with your replacement speedo should you need one. I'm hearing that the speedo gears in the tranny are expected to fail and they are no longer available. If you have the standard rear suspension, it seems like it would be difficult to find a place for a sensor to sense a target. Maybe you could fabricate something that would be welded to the inner U-joint half. In any case, you will likely have to get pretty creative!
