Thanks for that, but no, I will not forget it if OK with you!
Well, started the roof rail retrofit today. If time is not an issue, then not a difficult job at all - providing you have some basic engineering skills! The hard part is dropping the headlining. The secret here is not to rush it, and remember that everything at the top is supported by something underneath - so start by taking the rear seat out, and then all the trim panels working from door sills up. There is one nightmare of a screw under the rear seat belt plate for which you will need the smallest ratchet with a philips head that you can find.
The hole positions are not marked as such, but by placing the steel balancers in place, and using an 8mm drill, it is possible to mark the positions inside, then remove the balancers and then drill a small pilot hole on the mark. A quick check with the rails that the spacing is indeed correct, then from the outside, open up the pilot holes to 13 or 14mm to accommodate the balancer centres, refit the balancers, tighten them to a good fit, fit the rails and tighten with the special nuts.
As the rails are really decorative, I thought maybe black gloss them along with the shark fin and door handles to extend the black pack, so I do not have a picture of them fitted (maybe post one next week), and because the access points in the car are recessed, it was difficult to get pictures of each stage, but truly it is not difficult. If anyone wants to do this, then I am happy to talk through it - or bring your car to the South of France and I will help..!! But here is a pic of the finished holes with the balancer and retaining nuts required.
