Answered in the header thread.

They are B and E body brackets. Drivers side is a 340 mount, pass side is a 318/340/360 mount.

You need a bracket with the holes near the other side of the bracket.



Note where the holes are in comparison to the wedge looking bracket you currently have. The ones pictured are A body drivers side, 318 mount converted to 340 style on left and a std 318 mount on right.
