4 Speed console brackets
Either buckets and console or bench with no console. You can't put the console and a bench seat in the same floor. So the console brackets are just 2 pieces. No bench seat stop req'd.
That 3rd little piece that the aftermarket included... I'm almost certain its a tying brace for the added floor hump section. Sort of like the 4 added plates at bucket foot prints, Just a little something more to prevent sheet metal flexing. Someone with a OEM 4 speed floor could confirm.
