Most of the rear hubs were open like style E and F . Some of the newer cars such as the gen 6 used style A in both front and rear. There's choices in the drop down menu when selecting. Price is $2.00 per Hub, it was $8.00 per set of 4 but only had a few combinations. In order for me to have multiple configurations i had to set it up this way. Hub G is the most commonly used in the gen 6 era and on current xfinity and trucks .
