Looks like they changed to 6 holes and a black gasket instead of the usual 8 holes and blue gasket. Just bought it brand new from Summit Racing so I doubt it’s a knockoff. Still weighs a hefty 19.7 ounces which is exactly what the older design weighed. The Motorcraft version FL820 only weighs 13 ounces so I think Ford Racings supplier just changed the base plate design? Still seems extremely high quality overall.
