70 and 71 had clear or white parking lamps in the grill...72 had orange parking lamps in the grill. to tell the difference between 70 and 71...i think you'll have to look at the interior for that.

The only exterior differences I know of are in the front blinker lenses. The 70 models have clear lenses in the grill. Ive seen both clear and orange on 71's and I believe all the 72's have orange lenses in the front grill. Other than that I cant think of anything else exterior wise.

70 and most 71's look identical inside and out, except I believe the 70's didn't have the square exhaut cut outs in the back. The clear lenses in front were used from the beggining of the 70 year production to most of the 71 year production. It is reported that the amber lenses were phased in at the end of the 71 models. Interior, the horsepower tags are different for each year, you have to kinda be familiar with what was what for each year to know which is which. 72's shouldn't have the fiber optic indicators on the center console.

Only way to know for sure is to look at the VIN# on the windshield pillar. One digit tells the tale.

May I kindly suggest a copy of the "Corvette Black Book", avail at any decent Vette shop for less than $20. It will tell you everything (and MORE!) that you ever wanted to know about any early Vette ever made......... :yesnod:

Here are some more differences.

All -72s had factory alarm with the lock cylinder in the back above the corvette script. As it was an option on 70&71 aswell that only tells you that if it's missing you know it's not a -72.

The side grilles have some sligth differences eventhough they look very similar at first glance. My -72 has slightly raised ribs on the vertical edges of the grille while my friends -70 doesn't have them, I can't remember when they changed this. They also painted the grilles differently leaving the chrome visible on the ribs.

Front grilles have two screw holes at the bottom chromed part on 71-72 models but on most -70 models there are none (I guess they have studs of some sort and are held from the back). They changed this sometime during the -70 model year, my friends -70 has one grille with visible screws and one without!

The differences are small and as cars have been modified over the years many details have changed. For example the amber parking lights are illegal here in Finland so I use clear lenses at the annual inspection (but change the originals back afterwards...)

Ditto my 70. The drivers side has screws and the passengers side has studs. I can't prove they are original, but I can find no front end damage from a hit so who knows.

The tags on the air cleaner and console are also an easy way to tell as the cars had different engines/HP ratings each year. I also believe most of the 70 small blocks had open element air cleaners.

1970 egg crate grills on the lower fenders have just the horizontal lines chromed. 71-72 also have the vertical lines chromed.

1970 had the sweet engines but the Amber/orange parking light lenses look way better. The 71 has the fiber optic lights on the console. I don't believe any of the others do.

Hi,
I believe for the 72 model year the fiber-optics system which had been standard since 68 were no longer available, while the alarm, which had been an option since 1968, became standard.
Regards,
Alan

I generally first look at the front and side grills to see if it's a 70 or not.
Next I look at the tail light panel to see if it has an alarm or not… this tells me if it's a 71. (if it doesn't have an alarm it has to be a 71, if it has an alarm it could be a 71 or a 72.)
I then look in through the side window to see the configuration of the data plate. It changed from 71 to 72. 71 has 4 pieces of info on it, while the 72 has only 3.

99 out of a hundred other cars and you can tell the difference in a heart beat but these 3 years of Vettes and are so frustrating.
If anyone is gonna know it will be Alan though.
