[citation needed] A limited production (1000 units) convertible was a modification from the standard car by Touring of Milan, offered as a catalogue model by Alfa Romeo called the Giulia Sprint GTC.

Common to all models was also a 5-speed manual transmission and solid disc brakes on all four wheels, although at South Africa's Brits plant a few automatic 2000 GTVs were made for the local market.

Both categories were used to derive GTA ("Alleggerita", or "lightened") models, which were specifically intended for competition homologation in their respective engine size classes.

It was revealed at a press event held at the then newly opened Arese plant on 9 September 1963, and displayed later the same month at the Frankfurt Motor Show.

The Giulia Sprint GT can be distinguished from the later models by the following features: Inside the cabin the padded vinyl dashboard was characterised by a concave horizontal fascia, finished in grey anti-glare crackle-effect paint.

[5] The rear brakes featured an unusual arrangement with the slave cylinders mounted on the axle tubes, operating the calipers by a system of levers and cranks.

[6] Of these 2,274 were right hand drive: 1,354 cars fully finished in Arese, and 920 shipped in complete knock-down kit form for foreign assembly.

[10] The Giulia GTC was based on the coupé's body and parts, maintaining the same specifications and performance, with the cabriolet modification being carried out by Carrozzeria Touring of Milan.

Besides the convertible top, distinguishing features are the dashboard finished in black instead of grey crackle paint, and a script reading "Giulia GTC" on the boot lid.

[10] Through the production life of the model, several modifications to the reinforcement applied were made by Touring, apparently in an effort to increase the rigidity of the body.

Carrozzeria Touring was in financial trouble when the Giulia GTC was introduced; the company went out of business shortly after production of this model ended.

The Sprint GT Veloce was introduced at the 36th Geneva Motor Show in March 1966, and then tested by the international specialist press in Gardone on the Garda Lake.

The Giulia Sprint GT Veloce can be most easily distinguished from other models by the following features: Inside the main changes from the Giulia Sprint GT were imitation wood dashboard fascia instead of the previous anti-glare grey finish, front seats revised to a mild "bucket" design, and a dished three aluminium spoke steering wheel, with a black rim and horn buttons through the spokes.

The Group 2 (Version 2) cars were built with limited slips diffs and with different ratios in the gearbox and a selection of wheel widths 5", 5.5" and 6" on a 15" diameter rim as well as some other features.

Version 3 (FIA 5126 Group 1, late): Had high arches and solid ATE uprights, with no adapters as seen in the article in Classic Cars magazine page 88 April 1997.

No documentary evidence exists (in the Italian language) that black carpet was ever used by the Alfa Romeo factory in the GT Veloce 1600.

The result was that, on paper, the car had only slightly improved performance compared to the Giulia Sprint GT Veloce, but on the road it was much more flexible to drive and it was easier to maintain higher average speeds for fast touring.

For the United States market, the 1779 cc engine was fitted with a fuel injection system made by Alfa Romeo subsidiary SPICA, to meet emission control laws that were coming into effect at the time.

The changes resulted in significant improvements to the handling and braking, which once again made it easier for the driver to maintain high average speeds for fast touring.

The Series 2 1750 GTV of 1970 introduced other mechanical changes, including a dual circuit braking system (split front and rear, with separate servos).

The brake and clutch pedals on left hand drive cars were also of an improved pendant design, instead of the earlier floor-hinged type.

The interior trim was also changed, with the most notable differences being the introduction of a separate instrument cluster, instead of the gauges installed in the dash panel in earlier cars.

Record exist on the Classic Alfa Romeo register of a RHD GT 1300 Junior which was made and delivered to the UK in 1972 AR 1296169.

From 1968 onward, Alfa Romeo models for the US market were fitted with fuel injection systems instead of carburetors to comply with emissions control legislation.

[23] Besides the longer tail, a number of exterior details distinguished the 1600 Junior Z from the previous model: the arched front bumper was bulkier, the fuel filler was moved to the left hand side, the tail lights were larger items sourced from the 2000 Berlina, the door handles had black plastic housings, and the exhaust pipe was down turned.

Most customers were racers and had them further modified and tuned before delivery by Autodelta, which had become a wholly owned Alfa Romeo subsidiary running its competition department.

Marco Fazio of the Alfa Romeo Documentazione Storico confirmed on the Spettacolo Sportivo in September 2011 that "America" is the official type name.

The GTAm was initially built by Autodelta and was based on the US version of the 1750 GTV (Tipo 105.51) which was fitted with a SPICA mechanical fuel injection system to meet US emissions regulations.
