OK - this is a tough one given that GTVs with A/C are reasonably rare. I am trying to figure out the material of the washers below. Metal? Rubber? Other?

Alfa fastener catalog doesn't list it, so hoping someone knows. Part# 105.48.10.153.00. It's one of the washers that goes on the A/C mounting studs attached to the head.

Thanks!

There are definatley rubber washers used (at least on my car although I can't guarentee mine are original) I think 105.48.10.153.00. are rubber washers while 105.48.10.153.01 are the metal washers. In the picture below you can just make out a rubber washer between the metal one and the bushing - See this picture here:

When I get access to my garage over the next couple of days I'll have a look at my installation and will let you know. Also if you are using that bracket you will also need to spacer for the fan (105.48.07.235.01) to position this further forward to ensure this does not interfer with the pulley.

Here you go - measurements for metal washers

I don't know which side of the washer faces the bushing - incidentially the bushings contained within the AC bracket have the following number on the rubber# 82157.

My suspicion is that the inside diamater of the rubber washer (21.90mm) is large enough to suggest that this fits snugly over the raised section on the metal washer which has an outside diameter of 21.61mm. So the order would be - rubber washer > bushing > rubber washer > metal washer with raised inner edge facing rubber washer > swivel washer > nut. That said, my metal washer look closer to what is depicted in the Alfetta 2000 AC Manual so perhaps this is where my parts come from - I can't be sure.

Fantastic information. Thank you for taking the time to make the measurements.

I also have a factory AC car and need to do the same refurbishment and installation.
