Dan, you can build your MG with a mid and large size adjustable wrench,
vise grip and a long nose pliers. On the other hand once you start the tool
thing it becomes an addiction. Ever heard of Tool Junky? I would get
myself a set of metric and standard tools. Take a look at kobatltools.com.
These tools are beautiful and made by Snap On. I highly recommend you
visit your local Sears store. They have these new wrenches with standard C
mouth but on the eye of the wrench there is a small ratchet type device
that is just wonderful. As far as Harbor tools you can buy some stuff from
them but as the saying goes, In the end cheap stuff is expensive, Enrique.
