When you want to option a Heavy Duty shock absorber on a C10 you can use a shock from a C20. According to the parts book, the same shock absorber, group 7.345, is used on a K10 or K20 from 63-66 GM part #3197643 for the front and part#22012166 for the rear. The rear part number is a newer number that supersedes the original.
