I ordered a NOS craftsman kit, so it was USA made. Cost all of $11 and change and fit like it was made for it.... cause it was lol. No way I wasn't putting it back to factory spec, hell I even ordered a new kit for the matching 1/4" I have and it just came in this morning. The only reason I am even doing them is the rubber O rings dried out and its leaking grease out of and not staying lubed very well.Let us know how the rebuild kit from eBay works out and maybe a link to the specific item. I bought a couple cheap Chinese rebuild kits from eBay and was not pleased with the results. They were very “sloppy” or loose feeling. Yeah, they worked okay but I am always worried that when I put a load on them they will slip or fail. These were bad enough that I almost reused the old internals.
