Rattletrap,

Chev's of the 40's lists rebuild kits for the two state pumps....not as new as '62 and not listed by pump mfg.

For the cost of a kit, if available, I would think the the wisest choice would be to leave the rebuilds to the re-builders and pick up a new or rebuilt unit in the box. This is one of those things I don't feel it's worth my time dinking with, but thats my opinion!
