Well the ones i have found ac delco have a rib in the middle and wont fit the bracket .Not like the picture but I will look at advanced but have a feeling it will be a fail
Most of the Riviera guys I know are using the ones with the "rib" around the middle. The circumference is smaller so take and old inner tube and cut it so that it makes a band to go around the filter. You can then use the original bracket. Ed
