iirc the calipers mount on the front side...which is a no-no on a g-body because of frame interference, so if you swap sides the e-brake stuff will be facing the back of the vehicle instead of the front...better off to do the f-body rear discs and swap sides since the e-brake stuff pulls to the rear on the f-body, after you swap sides they pull to the front just like a g-body and it's do-able
