please dont kill me, looking for rear leaf shackles

That's probably the best bet. But you can do it with air shocks and shackles and shock extensions. It's not the best way but it will work.

You need to remember though on a leaf spring rear suspension, using air shocks completely negates their intended design. The springs are designed to plant the tires and lift the rear of the car. If the car is already lifted, that cannot happen and wheel spin will result.
