brands to buy when adding a leaf to a leaf spring

I was lucky, I junked a Demon and a Duster. I just pulled all the original 67 springs apart, and the same with one of the junkers

I took the original main leaf,

then added the two (same length) longest leafs one from the 67, one from the Duster

added the next two (same length) down..........and so on

I think I ended up with one more leaf added in number over original. It's just exactly where I want it and nice and firm

You can get the "hammer and bend" spring clips from any good spring shop
