Classic Alfa strengthening kit for trailing arm to rear axle brackets to fit all 750 and 101 Series cars. This is an essential modification for anyone thinking of doing rally or race events in a Giulietta. The brackets on the rear axle tubes are not very strong and after 45+ years they can be quite fatigued with potentially lethal results. These four laser cut steel plates weld to each side of the brackets and re-inforce them; simple but very effective!
