I bought an old Cornwell 3/4 drive ratchet a long time ago and then came across another one at a yardsale for $5, I know lucky right. The two ratchets are different and I researched it and found some information on alloy artifacts but I did not find that interesting drive adapter for the 7/8 drive ratchet. That adapter reduces it to 3/4 and can be popped out and put in the other side. The other ratchet simply pushes through. On alloy artifacts it just shows the 7/8 drive ratchet without a plug or adapter. I wonder is there a 7/8 drive plug for this ratchet? Both ratchets look identical except for the drive hole.
