I've got a set of Belltech shocks that are for 68-72 A bodies for stock to 1" lowered suspensions for sale. I had them on the blue/white '71 and they were pretty stiff riding so took them off.
The front lower control arm will need to be opened up slightly to get the body of the shock through it since they are pretty beefy.
Going on FB Marketplace soon for $75 for the set, so will sell to a club member for $50 bucks.
