Thanks Duemila & Alfahaze.
I have just started this rebuild project. Alfa knowledge and spares in South Africa are rare, so I need to make contact with experience.
Working through the process of testing and fixing EVERY faulty item in the car before I strip it, that way KNOW that it was working when I put it back.
I was struggling with dismantling the electric wing mirrors, but took a chance to get the mirror off, thankfully worked. Completely stripped and cleaned the inside and hey presto, is working like a dream again! Very confidence building. Also discovered that the motor inside is same as an 80's VW transporter or BMW E30 - good to know for future as they are in plentiful supply.
Now onto the Electric windows !! Making progress, so will keep pushing on.
Thanks for taking the trouble to respond - will be in touch in future I am sure!!
Thanks for the engine advice - will certainly take that advice when I get there!!
