Hi
Has anyone on here done a RHD to LHD (or vice versa, the concept must be the same) conversion? Is it as straight-forward as it seems it should be or should I prepare myself for unexpected problems? My car was originally a LHD Californian car that was converted to RHD. I am now spending a lot of time in France so I wish to re-convert it.
Thanks.

Haven't done the conversion myself, as the car I rebuilt was an original UK car. However, the job is straightforward and relatively easy, as the car was designed for ease of production for both LHD and RHD, as around 85% of the production was LHD, so all the necessary holes are already drilled and tapped to take the appropriate brackets/fixings. Specific LHD parts that you will need are;

A LHD Steering Rack (not the column, your RHD one and its brackets will work) make sure that any shims between the original rack and its two mountings are kept in the same place.
A LHD Dashboard.
Drive cables for the speedometer and tachometer if the RHD ones cannot be routed in a smooth path to work properly.
A LHD accelerator pedal and linkage - note that the RHD pedal box, master cylinder, clutch and brake pedals transfer straight across, and the blanking plate/rubber on the other side replaces the master cylinder.
New rigid pipes to connect the brake and clutch master cylinder to the brake junction fitting and the clutch slave cylinder.
LHD dipping headlamps if you are spending lots of time in France.

That's about it, although there may be one or two other items, like a LHD dashboard wiring loom, but you can get round that by extending the existing wires to right places if you are not a purist. Please ask away if there are any other questions.

Wow! It's nice to find that, sometimes, what seems as though it should be straight-forward actually is! It might be winter before I embark on the conversion, but I'll try to remember to report back when it's done.
Thanks Mark.

No worries. You are doing it the right way round as far as conversions go in terms of price, given the relative availability of LHD parts.

Aside from old originals for reconditioning, new LHD racks are available at around £200...RHD steering racks are like hen's teeth, so do factor in how much you could get for that on resale.
