>>>I don’t think it’s actually necessary to raise them initially. But it will be necessary to raise them to get the gearbox out. Once the gearbox mounting plate etc is unbolted from the body the gears will disengage and you can then raise the lights. They then need to be propped open.

>>>Up or down, it’s still hard to reach. It’s actually easy to reach from inside the wheel well, but it’s not possible to see it so you have to do it by feel.

>>>If you are lucky they will not break. If they do, you can still remove the switch and then once the plate is in your hand it’s easier to drill out the broken bolts. I would spray the bolts with a penetrating solvent and let them soak for a day before starting the job.

>>>It’s very easy. However, there are some very thin washers (they are actually acting as bearings) on either side of the broken gear and it’s easy to overlook them and throw them away by accident. Be sure to look for them carefully and transfer them over to the new gear.

>>>It’s much easier to do this job with the radiator completely removed, but of course that is a lot of extra work that is not really necessary. 

Good luck and please let us know how it works out!
