Huge shout out to Proto/BD, I had an older 3/8" ratchet missing the ball, a newer 1/4" ratchet that had a horrible action and a broken 6mm hex bit socket. Three or four weeks ago I sent them an email asking about rebuild kits for the ratchets. I got a reply the next day saying we don't "sell" rebuild kits but if you want to send them back we will look at them. Today I received both new ratchets and not a new 6mm hex bit socket but they sent me the whole set 4 - 10mm. Pretty damn good customer service, did seam a little odd they didn't just rebuild both ratchets but I'm not complaining. Unlike SK maybe the newer parts just don't quite fit the older tools.
