I just goggled sears cultivator and came up with tis old photo. I don't think you are going to find any vintage parts for those, rare as hens teeth. May be lucky to find modern garden tractor parts, but Sears is now completely out, went bankrupt a few years ago. Generic Sweeps may gotten new and could fit and other parts could be made if you can use an old one as a sample.
