Hello, Marina-88, Yes, I did it. You have to remove the steering-column, that means you will have to partly disassemble the steering
mechanism. Then you remove the screws around the edge of the cockpit
floor, screws from above, nuts from below, that means, You need two persons. The rubber sealing is sticky, You will have to use some force to lift
and remove the cockpit floor.
