I'm running a pair of buckets in my 46, has similar tub, to get the seats up at the best height I installed a thick piece of wood
on that tub. If I'd mounted these seats to the floor, would look like a lowrider.

Another plus with buckets in the 46 is now I can flip the seats forward to access that space behind the seats.
