Locating parts and advice for an alfa spider-1974

Hi guys - I'm new to this forum. I was given an old Alpha Spider 1974 as
a wedding present - and its sitting in a garage in Italy without a
license plate and a mechanic saying I need to change some things to get
it to pass its Italian mot.

I was told that ironically it might be cheaper to find the parts I need
in England - does anyone have any tips for me.

I need the following (and I'm hoping to preserve the integrity of the
car if I can)

- new windscreen wipers
- hi beam/low beam light switch? (devio luce in italian)
- break master hanging pedals (for alfa 105)
- clutch master cylinder and slave cylinder
- front caliper service kit and rear caliper service kit (rear 38mm)
- front and rear indicator light plastic covers
- Carburetor replacement for a Spica fuel injection system*


*Our mechanic said we should change this as its next to impossible to
get anyone to fix a Spica in the future as the skills are not around.
Apparently ours is ok at the moment (but for how long).

Does anyone have any tips or advice for me?
