Those are the right bulbs Xac. I popped a Vernier on one I have here and the 5mm and 17.5mm measurements tally. I'll order a pack of ten in the week as I need two plus spares and I'm sure you need at least four!
Drove the V6 today and found I had the steering wheel a spline out following the instrument bulb replacement. never noticed last night as it was dark but nothing irritates me more than a steering wheel that's not level when going straight ahead. 10 minutes and all fixed. I did disconnect and remove the airbag but did the job without touching the radio remote plug or fully removing the steering wheel.
That done I set about tidying and rearranging the garage ready for the arrival of a poorly V6. Not far into that job and Sid The Squid calls asking if he may nip over to replace his front brake pads and attend a few other small jobs on the Green Goblin. There followed a most pleasant afternoon indeed
Xantia_v6's poorly V6 will be arriving later in the week and then work will commence to see what has failed in the gearbox. I'm looking forward to it with some relish I must confess. Firstly though my garage has to be made ready and I cannot believe how much more stuff I seem to have acquired since I did mine

All of which has to be found a temporary home. That home will be the conservatory, much, no doubt, to the consternation of the cats...
I've loosely reassembled the EPIC pump I had in bits and that, along with the ML5 gearbox will now have to wait their turn...
