I am looking to buy some gauges for my 95z28.. a boost/vacum, and a air/fuel ratio gauge... The boost is mechanical and the airfuel is electrical.. I think i want to go with auto meter... How hard of an install would these two be and does anyone know where I can get better install directions from.. thanks,

 

I think they have an install guide on there site http://www.autometer.com/ if you have not already seen that.
