I was cleaning up and found the receipt for the Napa parts I bought to fit
the tri-star bolt heads on the CV joints, and thought I would post them
and get them into the archives if anyone should need them.

The NAPA part number for the tool is 2304, $6.80, and the adapter I got to
got to a 3/8 drive handle is 35741 @ $5.99

Probably didn't need the adapter, as a 5/16 socket should work, but I
bought it anyway. Just be sure to use some duct tape or something to  hold
the tool in the adapter so it doesn't pull out at the worst possible time.
