1970 L78 Nova question...

[67BelAir427]

I need to replace the gas tank on a 1970 L78 Nova. The car has a build date of the first week of April 1970. Just want to make sure that the tank I need is the one that does not have the "EEC" vent? I assume that the EEC tank was either a California emissions requirement or a late 1970 change? My car is a Canadian delivered car if that changes anything. Also, the Canadian built tanks sold on E Bay by Tamraz as opposed to the offshore tanks sold elsewhere? Any suggestions would be helpful. Also need the sender unit. Thanks, Marc
