Changing the chassis to a left hand driver

[voucht]

Hello everybody,
I'm new on this forum, and I've been looking for a post talking about my problem before posting that, but I haven't really found what I wanted.
I'm building a Haynes roadster (Chris Gibbs book). I want to make a left steering wheel chassis, as I'm living in Sweden (and, on top of it, I'm French !) If I build the chassis as it is described in the book, the room in what is the passenger side will be to small to fit a pedal box for the driver. My idea is to reverse all the non-symmetrical tubes, which means the transmission tunnel, U7 and U8. But my concern is : will the gearbox fit with such a change ? I will use a 5 gear T9 gearbox from a 2.0i Sierra, but I don't have it yet, so I can't make any try. I guess the gear box is perfectly symmetrical and centred, so it should not be any problem, but could anybody please confirm I can do that ?
I'm sure some of you are not in a country where people drive on the left side of the road and might have had to adapt the chassis design to make a left hand driver car.
I have to start the building of my transmission tunnel now, so I want to be sure.
Thanks to all of you.
