Fitting seat pans to the seat

[Limey57]

I'm fitting the seat pans to the Ranchero (same as arrowed below), I know there should be brackets at the front of them, but does the back of them just screw straight to the seat frame or should there be brackets at the back as well?  I've searched various pictures online but nothing is clear.

There is a bracket for the rear to have a bit of clearance from the bolster to the seat.

That's great, thanks
