There are no cummins-specific leaf springs for the rear. Heavier trucks have 3/4" eye bolts. Lighter trucks have 5/8". I have cummins trucks with either size eye bolts. I have gas trucks with the 3/4" eye bolts.

Check your spring hangers for being rusted through. If you need to change these, it really adds to the labour. At which point you can consider mounting them lower, or further apart, and even run longer springs (better ride). Jungle over at RCC has a stout shackle-flip setup that can eliminate the block. Chevy leafs (56" or 63") have more arch to them than Dodge. (stock vs stock.)
