In the process of rebuilding a 71 dart and want to do a dash my own way. Looked at fast lane west inserts, but they don't appear to work in my 71. Thinking about ordering a new rallye from year one and then putting aftermarket gauges in it. has anyone done this or know if it can be done? And do I need to buy or make special bezels or anything else for that matter? Hope to do speedo and tach in large holes, fuel in small center hole and then oil psi, water, and volt under dash. Thanks, JP
