Leaf Spring bastard pack

I'm going to take a leaf off my old springs and add them to the new HD springs I installed a few years ago.

I want to get about 1.5" of lift.

Should I cut the eyes off the old springs and use the main leaf? Or should I use the next smaller one? The main leaf looks thicker.

Thanks.

Cut the eyes off the old main leaf and add to your spring pack. You should get about 1.5" of lift. YMMV.

Thx ... anyone know of a good homebrew substitute for spring liner? I thought of using plastic from a coolant bottle, but not sure how to make it stay in there, since it has no lip.
