Cord: I was a dealer for several years. While I did "procure" a beautiful collection of tools for my personal collection

, I did not make it a point to stock repair kits.
I do, however have some close friends nearby who are still in the business, and could probably help you.
Ideally, if you could find a dealer in your area, he'll probably fix it right in front of you free of charge (he should, anyway).
A word of caution: If he likes what he does, and therefore has a clean, well-stocked truck, you could be in for some droolin' over a batch of really nice product and could be faced with some impulse-buying.
That aside, another option with which I am less familiar, Snap On has a pretty thorough website

, although I don't know if they sell repair kits (their 3/8 ratchet, BTW, has a gozillion different versions, so you have to get the right kit) . You can expect, if you were to buy the kits, to spend almost $30/kit. I don't know if they have an exchange deal on the web.
Finally, if you're in no hurry, you could send them to me, and I'll probably have them back to you within a couple weeks, if I stay diligent on the task.
I do guarantee I'd return them, it's just busy stuff this time of year, etc. You know....
