As you can see, one side of the mount is threaded, and one side has a larger hole.. both sides of the K-Frame mount have holes the same size as the non threaded hole on the mount.. with the mount sitting flush the non threaded side does not line up.. this is a 1970 B-body K-Frame, the mounts are from 440source.com...... What am I doing wrong, or missing.. when the mounts are bolted in it is not sturdy at all.. it wiggles side to side, and up and down..
