@sudboy1490, thanks for the link, unfortunately only information available on the "deluxe" version and not the one you are using :-( I'm mainly looking with great interest to this forum and seeing with how much dedication Alfa's are treated and restored here.
The restoration of my Giardinetta can be followed on the Giardinetta Internet page (see URL below). Starting a thread here would be redundant I believe.
The work you are doing on your S1 TI looks very good. No rushing and no short cuts, keep it up I would say.
