As Alfa Romeo has been gone from these shores for over two decades now, finding replacement parts at a local auto supply will be difficult. Those with vintage American autos, say a 66 Mustang are fortunate enough to be able to drop into almost any parts supplier and pick up parts both easily and cheaply. We alfa owners in the USA are not so fortunate. So, bringing some spares along the drive is well advised. I’ve put together a collection of easy to carry parts.
Fan Belt
Fuel Hose
Radiator Hoses (upper and lower)
Distributor cap and rotor
Water Pump and gasket
Fuel Pump, gasket and Bakelite
Hood release cable (mine was recently repaired)
Clutch slave cylinder
Fuel Filter and Glass bowl
Alfas on Route 66 
that’s a good kit!
