Spring eye question

Not 100% certain, but I believe early A ('66 and down), also '62-'63 "B" body used the same 20"/35" segment 55" leaf. My 52yr. old mainleaf had a hairline crack running
right through the center-bolt, the perfect reason for an upgrade to newer and better!Total on My new pair w/shackle bushings, eye bolts(5/8"), & fitted with the larger bolt eye
bushings was $347 shipped! Tad further to You from Danville PA, but not too far. I stayed w/rubber eye bushings, the 5/8" sleeve is much thicker than the OE, so it is beyond
just the diff in bolt dia. ..... read a lot less rubber to give. Also the bushing is a higher durometer unit to boot, there will be much less movement there.
