No the AMD trunk floor pans are 70 - 73 and up design
Sell your 70 tank that you bought as a 69 - 69 tank because that what it is. It’s not a 70 tank. Like I said no one makes a 70 tank. It’s a one year only tank. Everyone one that sells gas tank advertises the 1970 gas tank wrong besides 521 restoration that they tell you.
