Gentlemen, I wonder if anyone knows whether there were any maximum dimensions for rear wings during the 1972 F.1 season?

From Appendix J Article 296 in the 1972 FIA Year Book:

g) Coachwork: no part of the coachwork, with the exception of the safety roll bar, shall exceed in height a horizontal plane, 80 cm above the lowest point of the entirely sprung structure of the car.
In other words, a car with its wheels and the mobile suspension elements removed, but without regard to the roll-over bar, must pass between two parallel planes separated by 80 cm.

Formulae 1 and 2
Behind the front wheels, the coachwork shall not exceed a maximum width of 110 cm.
The coachwork ahead of the front wheels may be extended to an overall maximum width of 150 cm.
Nevertheless, any part of the coachwork ahead of the front wheels, exceeding an overall width of 110 cm, shall not extend above the height of the front wheel rims.

These regs were the same as for 1971. For 1973 the maximum width of coachwork between the front and rear wheels was increased to 140 cm. The maximum width of the rear wing remained at 110 cm.

Thank you, Tim. I will do some measuring next week!

I do hope we don't discover that any car of that time had an Unfair Advantage.

Some did manage to exploit those rather loose regs a little:
