Rear Coil Over 72 El Camino install Replacing stock springs

[Danny72]

Hi, So I'm about to throw on rear Qa1 single adjustable coil overs with 150lb springs for rear and am arguing with my dad that the springs on the coil overs replace the springs on the rear end meaning that where the stocks springs are, we take those out. If someone can let me know I'd really appreciate it. I want to get them on as soon as possible. Thank you.
