You really need to examine what the FIA rules were at the time and consider if it was possible to set the car up with alloy panels in the day. Since we are discussing the 1750 GTV.

Here is some details from the 1968 FIA Appendix J
Category A
Group 1: Series production: Touring (Min quantity 5,000)
Group 2: Touring cars (Min quantity 1,000)
Group 3: Grand Touring (GT) (Min quantity 500) [FIA 599 GTV]
Group 4: Sports Cars (Min quantity 50)

Category B
Group 5: Special touring cars (Min quantity 1)
Art. 267. - Definition and specifications: vehicles deriving
from cars recognized in groups 1 and 2, of which they have
kept the original coachwork, but which have been submitted to
modifications and/or additions not authorized under articles 257
Group 6: Prototype Sports cars (Min quantity 1)

Here is some details from the 1969 FIA Appendix J
Category A
Group 1: Series production: Touring (Min quantity 5,000)
Group 2: Touring cars (Min quantity 1,000) [FIA 1576: GT Am, and FIA 1565: GTV]
Group 3: Grand Touring (GT) (Min quantity 500) [FIA 1565/1/G 500 cars]
Group 4: Sports Cars (Min quantity 25)

Neither the shape nor the original materials of the standard coachwork may be modified, the chassis may be reinforced but not lightened or cut.
Group 6: Prototype Sports cars (Min quantity 1)
Prototype sports cars must be fitted with a double braking
system such as specified under.

Rules changed for 1970/71 FIA Appendix J
Category A
Group 1: Series production: Touring (Min quantity 5,000)
Group 2: Special touring cars (Min quantity 1,000) [FIA 1576/3/2V GTAm] [FIA 1565/3/3E GTV]
see page 67:
z) Recognition of an option: the recognition of an option will be granted only if the optional equipment is available freely at the manufacturer’s or his dealers’ for any one wishing to purchase it. It must be mentioned in the manufacturer's catalogue of spare parts for the model concerned and properly identified.
aa) Optional equipment which may be recognized with a minimum production of 100 units per year to equip 100 cars:
....
Nevertheless,
...
— Lightweight coachwork elements, such as aluminum doors, plexiglass lateral windows, glass fibre engine bonnets, etc. Nevertheless, the basic weight of the car mentioned on the recognition form shall not be modified. The recognition of light weight elements is only meant to compensate the manufacturing tolerances and the fitting of some optional equipment which results in an increase of the basic weight.
Group 3: series-production grand touring cars (Min quantity 500 to 1,000)
Group 4: special grand touring cars (Min quantity 500)
Group 5 : sports cars (Min quantity 25).
Art. 269.—Conditions required for recognition : the 25 cars shall be identical as regards the following points:
a) Coachwork: general line, materials of construction, shape of wings and bonnet, number of doors. Small modifications will be allowed when made necessary by the different uses of the car (circuit or road events),

Category B : experimental competition cars
Group 6 : prototype-sports cars. (Min quantity 1)
Furthermore, prototype sports cars must be fitted with a double braking system such as specified under Art. 269 f, and be equipped with safety fuel tanks of an FIA approved type (Art. 272).

What does it all mean for each year?
Documents
1968 to 69: Group 3 1750 FIA 599 [ 500 Cars]
1969: Group 2: Touring cars (Min quantity 1,000 cars) [FIA 1576: GT Am, and FIA 1565: GTV]
1969: Group 3 FIA 1565/1/G 500 cars
1970: Group 2 [FIA 1576/3/2V GTAm 1000 cars {alloy doors and boot lid}] FIA 1565/3/3E
1970/71: Group 2: FIA Rules: Special touring cars. If factory made full alloy bodies as Optional equipment which may be recognized with a minimum production of 100 units per year to equip 100 cars, other wise just Lightweight coachwork elements, such as aluminum doors,
OR

Or
As for full alloy bodies could they have been cars built in group 5 or 6 ?
1968: Could have one or more full alloy 1968 GTV in Group 5: Special touring cars (Min quantity 1)
or
Group 6: Prototype Sports cars (Min quantity 1)
1969: Could have one or more full alloy 1969 GTV in Group 6: Prototype Sports cars (Min quantity 1)
1970/71:
Group 6 : prototype-sports cars. (Min quantity 1)

There may be other possibilities. You have to look at what others were doing like Angelini who may have ran cars in these Groups: 4,5 and 6. Some one with Angelini's book could provide us with some details, if he ran a car that looked like a 1750 GTV in full alloy.
There was an alloy looking 1750 GTV here in Australia by using a GTA as a start point. Technically the Australian modified car could have been a group 5 or 6 GTV 1750 car.

So it was possible!
As always my opinions.
Cheers Steve
