To install an underdrive pulley, you need a shortened 24mm socket to do the job right -- there isn't enough space to get a torque wrench in there with a standard socket. Since people are starting to get their pulleys from the BBI group-buy, and at least a few people will install it themselves, I thought folks might like to buy a shortened socket, rather than going through the hassle of shortening one themselves (it's a pain without access to a lathe).

To make life a little easier for the do-it-yourselfers, I can cut down sockets on my lathe. These are 1/2" drive, NAPA store-brand sockets with a lifetime warranty (although, I don't know if the warranty will still be valid after shortening). Cost is $10 plus shipping (shipping by USPS priority mail, within the US, would run $6, which includes the cost of packaging). Please PM or email me if you'd like one.
