I am going to look at a 94 gs and they owner said the light on the tach is burnt out.  How easy of a fix is this?  Thanks for the info.

it's actually really easy.  when mine burnt out it probably took me all of 10 minutes to fix it.  just unscrew the tach from the housing, pull it up a little.  on the side you'll see a little black shoe-like thing.  just pull that out and the light is held in there.  it's a simple replacement:  pull out the old one and pop in your new one.  i can't remember right now what kind of light it is, but if you search for it you should be able to find it posted somewhere.
