This is copy of one of the best looking gas caps you will ever add to you car. Polished chrome with a flare. The "'flip top' and 'push button' opening cap was made famous by some of the most historic cars ever raced at such famous tracks as 'Monza' and 'LeMans'. The design was conceived for function not looks- it allowed the racer to fill the gas tank faster.
The actual cap screws onto a special brass adapter that is a tight press fit onto the neck of the tank but should be glued for safety.
To fit the collar for this cap you will require 10mm(0.3937")just over 3/8" of petrol tank neck accessable above the body seal to allow fitment, many later cars do not have this much neck protruding so check first.
Neck size 2 1/4"(57mm).

Really good cap
This is the best cap I have ever had on any car. You open and close it with just a finger, no screwing on. Awesome at the gas station.
A catch is that on my '64 filler neck, the threaded brass collar that comes with this cap is too tight. I should have sanded down the tank neck first. Instead I made the mistake of heating up the brass threaded collar and tapping it lightly on the tank neck with a hammer. This resulted in losing the ability to point the final position of the cap where you want it - say horizontal or vertical.
So mine is pointing rather limpy downwards, which at my age is to be expected.
