67 k10 4x4 rear springs

[dgold_881]

I have a 1967 short bed k10 4x4 and would like to replace the original rear springs. The previous owner put a 2.5" lift but it only added a block for the rear. Does any of the manufactures make these odd size springs anymore? Or is there a hanger substitute that will allow for the use of the more common spring sizes that I can retrofit to work? I tried doing a search and it only came up with 1972 trucks. Thanks for any help.
