Great going Joao and so good to see another JZ being saved from the crusher!
I'll go through al your posts to see if I can be of help.
Many of the parts found on the JZ that are not "specifically Zagato" come from the 1300 Junior Spider which served as the basis for the JZ.
Consequently, the rear view mirror that you need is the same as from that Spider. A lot cheaper than when you are trying to find a mirror for a JZ and exactly the same thing...
Please note that the 1300 JZ did NOT come with carpets but with rubber mats only. A set consists of 3 pieces; the front two are again the same as for the 1300 Spider. I am not sure if the third one is also identical to the Spider. The sets are available from most parts dealers who supply current production rubber items for the 105 series. (Re-originals, Cicognani etc).
Here is a 1969 photo of the dashboard of the 1300 but please note that this was a prototype so there might be small differences.
The arm rests are notoriously weak on the JZ's and are often replaced by the ones found in the 1750 Berlina... this is also the case with yours... The originals are the same as for the post-1965 Giulia Super (105.26) and are devilishly difficult to find (looking for a LH example myself...).
This is what it looks like:
The interior door panels are NOT original... I'll see if I can shoot some pictures of originals on my cars.
The holes in the back of your car are NOT original.
The rivets in the back of your car are NOT original.
The original steel wheels for the JZ are indeed coming from the 1300 GTAj. These are the only two Alfa's that had these wheels as original equipment. Again, very hard to find as many JZ's had them swapped for mags over the years and the steel originals were usually scrapped...
I'll try to find some more answers for you.
In the mean time, may I aks you to send me a PM with the serial number? I would love to enter the car in the register @
