Hi,
There were (are?) also center consoles with locking lids... also a nice center armrest. I've got one that fits in my TR4. Most of these just slip over the driveshaft tunnel, but might best be held in place with a couple screws. Some had (have?) other features such as built-in speakers, lighters, change holders, p'haps even cupholders. There are modern repros, but might or might not look right and "period correct" in your car.
