Hello Thomas,
Welcome to TM.
I have a 1993 +4 T16 and although I am 1,88m tall, I have no problem fitting in my car. Sometimes, when using the clutch, I did bump my left knee against the dashboard lighting dimmer control but I've solved that by removing the dimmer control button.
As already suggested: have a look at Brands Hatch Morgans (I did).
