Update on spring rates (which I am aware is likely the most fascinating thing you will read today), they're going to be 40 front 90 rear, according to the invoice for said springs I just paid - so 20 lower at each end than the coupe due to the cab being somewhat bendier.
If anyone has a recommendation for where to stay near CG do shout - I'll likely drive up on the Sunday, stay that evening and the next.
Right- continuing to solve problems:
On rough roads I'd noticed an annoying noise, took me ages to track it down to the sun-visor, which has a flap that one opens to both reveal the vanity mirror and illuminate the lights to either side of it.
The springs in the flap have made a bid for freedom at some point in the past - successfully it would appear, so the flap flaps up and down over rough roads.
So today I swapped both visors for new - the left had one still had springs but they were very weak and I thought I may as well do both at the same time. New part excitement!
Part numbers if they are useful to anyone:
This turned out to be a ridiculously easy job, requiring a trim tool (thin) and a Torx T-25 driver.
If you want to do this yourself crack the roof open as the retaining pins on the leading edge of the roof locate into sockets on the sun-visor housings, this has the additional benefit of giving you plenty of room to work.
Remember- safety first, fixing second:
Pop this cover off:
A trim tool makes this easy:
Then take your T-25 driver and remove two bolts per visor, both underneath the tab you just removed:
Then simply pull the other end of the visor out of the clamp, the unit is now free of the car.
Out:
Installation is the reverse of removal.
All done:
