I note that you make reference to parts in the UK.
As there are no details in your profile I will assume that you are resident here.
There are some very good leads on this site for all your needs (and wants.! )
A number of experts are based in the UK - Eric Harrison being our 'guru', but he has poor health and has recently handed over the reigns of running the 2000/2600 register to Andrew McInerney. Take a look at -
www.alfa2600.co.uk
Will you be taking your 2600 to the National Alfa Day on June 19th - (NOT 27th as on the above site as it hasn't been updated from last year)? Are you a member of the AROC UK club? Plenty of friendly help there too - although getting to be a few too many chavs in modified newer Alfas for my liking! It's is well worth it - last year I met a 'guru' from Australia who was very friendly and helpful.
How about posting some pictures?
