Ha, so glad that you mentioned "a dry sunny day" in the singular
It is indeed a super county to live in, but the rain is the price we pay for a "green & pleasant land" in them there dales (my other car, when it on the road is a MGB Roadster and I'm also heavily into motorbikes, so a real glutton for punishment)
In the defence of my local dealership, the guy I spoke to runs the spares department. He is very pleasant and keen: but also very young, and isn't a spanner man.
Although I foresee no problem I will post a query under the suggested heading: so saying i may in all probability order it tomorrow (I could buy one and do it myself, but the quoted price is fair enough) so the question may be answered within the next 24 hours
I look forward to much advice, as I may keep this car for a few years
Once again thanks a lot for the reply
