Handbrake boot on the 1750 coupe.

[alfagtv100 (Biggus)]

A question to 1750 owners.
Does anyone know where to source a quality replacement for the handbrake rubber boot?
I replaced mine with a rubber one which looks great but has shrunk over time.  I am often told "They all do that".
Has anyone found ones which don't (shrink)?
As an alternative, what do people consider to be the nest leather or vinyl alternative.  I am thinking something which follows the shape of the original rubber piece (not huge and baggy).
There are options from the UK but I have not seen how they look on a car.
Any help would be appreciated.
Cheers,
Marco.
