Open it up - it won't cause any problems to do so. You can check the rotor screws and blue locktite them at the same time.
There should small Mitsubishi diamond logo on it and there may be a dot of light green paint also. The paint dot was on the ones I bought used.
Here's a link with photos -

It's the 15th photo and about 1/3 down the page showing the logo and paint dot.

I looked to last night and could not see any date codes when installed on the engine. I was more interested in getting tunercat to talk to my 95 than ID the opti on the spare engine.
Thanks for the info guys! Now I will know when I year down the engine of ours worth keeping.
