I have a 159 auto you can try out.
As for the 147 wheel take a look on e-bay, you might also want to post a picture of the wheel you need some one on here will have one or will be able to help, £160 sounds like a lot of money.
I'll have to contact you out of forum to try the 159, I guess you must (or be associated with) Autolusso who supply Alfa's? It'll be a while as I do not think you are local to Yorkshire!!
Good Idea on the wheel, I'll photo it and post it on the Forum. Is there a proper spot for this kind of posting? Oh and the £160 has grown to
£240 plus VAT = £275, ouch...........
Thanks for nice comments, I was worried my inexperienced post would get shot down in flames.
