I have made a list of all the Round Head Fine Tooth(RHFT) ratchets with the knurled speeder on the bottom, and all the repair kits are interchangeable. I have tried a couple and they are the same. Some of the older craftsmans have a through post quick release design, and that is no longer in use, other wise kits are the same, still available from Sears, Danaher. Also some of the older Easco, K-D ratchets were non-quick release(NQR) and if you get a current rebuild then ratchet will now be quick release. I have seen rebuilds from K-D, Allen, Napa on line, if you cannot get a warranty from either Sears or Danaher. If there are other models that I don't have listed let me know, these ratchets have been in production for 40 years so there may be some odd balls out there. Also added a Ridgid, it is sold with a 960 roll groover to operate it, but is an Allen brand clone, and can be bought buy it self online or through Ridgid. Also another Ridgid sold with a 915 is a 1/2 long handle with a 90 degree bend on the end of the handle.
