If anyone is wanting their RP ratchets rebuilt, I'd recommend doing so now.
1)Sears closing many stores and ACE hardware I can confirm doesn't and likely Lowe's will no longer perform this service.
2) Even the modern version of the kits are pretty pricey on eBay
3) I have 4 Sears near me, I know I am lucky, and of the 4 none are officially closing even as of the latest list. Aka they are all fairly healthy. *However* of the 4, only 1 store still has any 3/8 or 1/4 kits left. Stores CAN NOT order any more kits at this time although it appears Sears still has some. The other stores offered to order new ratchets shipped to my home, I declined to give up my USA.
4) There are sizeable benefits to be had by getting a original USA RP rebuilt. See below. First, never give Sears your old ratchet guts. Pull the snap ring and take everything out, giving them just the handle, they will still rebuild it.
If you are lucky your store still has kits. The kit will give you a few nice pieces to improve your original. A slick metal charcoal chrome selector lever, a less stiff pawl spring, and a more pointed pawl. Utilizing these pieces, along with your original USA drive head, snap ring, check ball, and retaining plate you can improve your clunky later USA RP far better than it ever was new.
Most people won't care to do this, but for me it made all the difference in the world in the action of the ratchet and overall smoothness. And since the kits are totally free, with no downside if you pre pull your USA guts, there is no downside other than the time to drive to the store and if they happen to have no more kits.
I would recommend keeping the USA drive head if still in good shape as well as the retaining plate and snap ring. The Chinese parts arent quite the right thickness as the original and as a result can create some slop when assembled in a UsA housing. At the least retain the USA cover plate and snap ring.
*Note* they don't stock kits to rebuild the Chinese ratchets at all, they will just give you a new one. Nor any of the finer tooth ratchets, although one store I visited did have a USA made kit for a 60t 1/4 drive so YMMV.
