Seeing if anyone has the knowledge to help me out right quick. I have a 47 ford coupe sitting on top of a 94 mustang. I need gauges. Want gauges to fit in the 47 dash, but need them to match up with the mustang engine, trans etc etc .. is there something I should be looking for or keeping in mind to match them up so they all work properly? Thank you for any help anybody can give me!
