Recently bought a cheap throwaway 3/4 socket set and found out it had a Cornwell har-5 ratchet mixed in when I got home. Unfortunately it's just the head but I'm looking at trying to hunt down a dealer, one was spotted an hour away from me last month, and buy a bar. As far as I know the bar is compatible regardless of age. Also not sure on the pin or screw to hold the handle on. I'd like to get a rebuild kit too since I believe it's an older ratchet, it has the spanner screw plate instead of a spring clip which I'm not completely sure they use on the 3/4 drive in the first place. Hoping someone on here might know more about them and if the rebuild kit works in older units.
