Hey Martin, great to see you on here.
Paul, also keep in mind the later Harrisons have a wider tunnel. So in the early cars it was easy to fit in seats like MX5 etc, it might not be such an easy fit now with the later chassis.
Slowy, on of the big advantages of the G-Force is that great body shape they have. What I call the early RMC shape and we know why that is.
