Yup some of it came from them.
A fair chunk of the thinwall came from
http://www.autosparks.co.uk/ and the wiring module's from
http://www.cbsonline.co.uk/Other odds and ends along the way have also come from Ebay - particularly when it's just been one bit (e.g Dash warning lamp or starter terminal) that I needed as the P&P tends to work out cheaper than using the above suppliers.
Only popped back to the computer to see how to get at the internals of the indicator stalk - think I've got that sussed now as well.
