1967 k20 rear leafs

[kernalklink]

i was hopping back and forth across my truck installing my under-box gas tank when i heard a "pop" - i knew what it was when i heard it - got to looking and both primary leaf springs are snapped in front of the axle.

the only thing connecting the springs to the axle is the clip that holds the 2 springs together - scary -

I can't for the life of me find direct replacements - every company starts on 69' and up-

i need to know what leaf springs can directly bolt in place of the factory ones

i suppose i could get the mounts and springs from another truck but i was hoping to do it cheap and easy.

any suggestion will be greatly appreciated
