Please see my post in the 105 forum http://www.alfaclubvic.org.au/forum/index.php?topic=9395.0 (http://www.alfaclubvic.org.au/forum/index.php?topic=9395.0). New to Sydney, and need all your helpful advice.
Have you called Rob Panetta at Manning Motors in Brookvale for advice? This is the best advice you will get.
Agree, Rob is a top bloke and a fountain of knowledge re 105s. Manning motors has an excellent reputation.
