Hi Pedro
Firstly welcome to the forum and if you have any questions please ask away.
The turn signal lamp you have asked about are really hard to find! the LH unit ADU3017 is in stock @ MossEurope but the RH unit ADU3018 issadly not available new any more! At a push you can use two LH units but you will have to drill some new hole as one will be upside down! Good luck with the restoration Pedro.
