I had a bear of a time getting the engine plugs out. Here is what I have.
The plugs are 5/16 square head, they can be removed with a 5/16 8 point socket.
Here are some part numbers:
Proto: 4710S Socket 1/4'' Drive 5/16'' 8 Point
Snap On: Socket, Double Square, 5/16", 8-Point Stock #: TM410
Craftsman: 5/16 in. Easy-to-Read Socket, 8 pt. STD, 3/8 in. drive Sears item# 00945791000 Mfr. model# 45791
These are special order items. Since I had already damaged my drivers side plug too much to be removed I had to try with vicegrips until the head was rounded enough to fit a #2 extractor over the head. The extractor bit down quick and the plug came right out.
Not a big deal to me, but someone with less background in removing parts from well seasoned engines (to be read old rust buckets) may have a difficult time.
