Welcome to the forum
Were they power seats?
If not I would see if you can find one to "test drive" that has power seats, and see if they go lower.
If they do then you can get the 2007 and swap to power seats, yes any year Ranger seats can be swapped.
Non-powered seats are usually set for average height or shorter, like pants, lol
You could probably cut and weld for it to be lower, but a swap with another non-powered seat set would probably not change much
Also look here for other seat swaps: http://www.therangerstation.com/tech...ry/Seats.shtml
I am tall as well, so it is indeed a deal breaker, nothing worse than having to bend your neck to look at a stop light, or feeling the headliner touching your head.
My 1994 Ranger fits perfect, non-powered seats, but I am only 6'5", I assume you are taller
