70' Coolant Over-Flow Tank?
There was no expansion tank on 1970 L46 Corvettes, with or without AC.
This is not the case with 1969 L46 Corvette's.

FWIW: If your cooling system is working correctly there is no need for an overflow tank. I can run my 70 L46 on a 100 degree day, with the AC blasting, in stop and go traffic, and the temperature always stays between 180 and 190. Even in the worst driving conditions the car never overheats. When I first bought the car the lack of an overflow tank concerned me, but after checking the complete cooling system to make sure everything was up to par I now have no concerns and the car never pukes.
