Thread pitch 1.25 mm. Rod/Strut Coupling Rod. Fitting side Right / Left. Fitting position Front. Product details. These spare parts are not original. They are an alternative to replace the original parts.
I've been through links and then some with my Alfa 156. You need to have a flange besides the ball you can hold with a 16mm spanner as you unscrew. These ones have it and finishing is top quality too.
