Hi Richard I am afraid I can't help if it's an original Alvis nut that you're after but I bought 3 new ones last year from Chris Prince and they look great! I made 3 studs from a length of brass threaded rod as the studs were missing from the cylinder head. Incidentally have you painted your plug shield or are you polishing it? I painted mine black and it looks smart enough despite a bit of alloy corrosion. Kind regards Posted by drdowhitt 06/06/2017 21:39:50
Greetings Jon, I too have a set of Chris's for everyday use but am trying to complete a set of original ones to keep for special occasions. I had my shield powder coated gloss black and it looks the part. Regards, Richard Posted by RichardWallach 07/06/2017 16:45:46
