Where did you see it was moved? Still says this Sunday on N Oakland Facebook page.
Talked to a couple of guys that work at the PPG's at our cruise-in on Monday and both said it was cancelled and Dave from NOMM posted this -

The North Oakland Mopar Muscle (NOMM) all-Mopar meet at the Packard Proving Grounds, originally slated for 4/26, has been moved to
September 20, 2020 —assuming Michigan moves to Stage 5 before then.
Car-show vehicles can be registered for $10 (for the owner and one guest), from 7 am to 9 am day-of-show; swap meet spaces are $25 with setup from 6 am to 8 am. The show’s open-to-the-public times are 8 am to 3 pm.
There are 15 award classes plus best of show, and spectator admission of $5 (children up to 16 are free). The event is no longer rain-or-shine. Food and drink will be available for purchase on-site.
The Packard Proving Grounds, on 49965 Van Dyke Avenue in Shelby Township (between 22 Mile and 23 Mile), is the historic Packard facility, and some company buildings remain for tours by the public.
Don't know why their FB page hasn't been updated since a lot of folks look at that.
