I'm wanting to keep the leaf springs and i-beam on the front of my '30 Chevy truck, but also want put in new spring hangers. I've done a far amount of searching but the only thing I've found that match the exact same spring eye-to-centers are General Springs 1937-1946 Chevy truck. Will call them Monday but am guessing likely the shackle hanger/leaf eye dims are different? Has anyone done an upgrade (even wit different year range) keeping at least close to the original dimensions? Thanks.
