Lower Seats for head room

[AlfredW]

I am looking at a 2007 Ford Ranger FX4 Off-Road SuperCab 4dr 4WD.
It has the original split bench seats.

I really like it but my only issue is head room.
I have reading through various forums trying to find out about replacement seats that will sit lower thus creating more headroom. I have no problems with the legroom, just the head room. It would be great to be able to get 2-3 more inches space.

Thanks,
AlfredW
