ok so i cannot find the spanner socket anywhere. well i havnt tried matco or any of the other tool companies but i wouldnt get it this weekend wich is what i need. my intructors at school did not have it, and our tool room did not have it. i tried oreillys and they didnt know anything about the adjusting sleeve or the spanner. i stopped by my work and only a few guys knew anything about the adjusting sleeve and nobody had the socket either, i also checked our tool room and had no luck. if i cannot find this spanner socket this weekend, i will try matco or another tool manufacturer. so anybody have an idea where i can find this spanner socket this weekend? that is all that is holding me up right now.
