Right side mirrors were optional on LHD cars. I saw one recently on Ebay, opening at over $100!

Depending on year and model, original Fintail tire sizes were 6.70x13, 7.00x13, 7.25x13 or 7.50x13 bias-ply tires. My '60 Fintail 220S is currently fitted with 185/80R13 tires, the modern radial equivalent to a 7.25x13.
I'm switching to 14 inch rims as it's now difficult to find quality 185/80R13 tires.

Happy Motoring, Mark
