Custom dash?

[84chevyguyid]

I want to add 2 gauges to my cummins/chevy crew cab dash, need a boost gauge and a pyrometer. Two essential items when you start turning up a diesel. My plan is to move the right side ac vent down where the radio currently resides and add the two gauges to the spot where the vent was but make it look factory using the 2 holes with the gauges recessed like the other gauges are. I am going to have air ride/assist on the front and rear suspensions so I needed an air guage also. I went to the truck wrecking yard the other day and scored a guage cluster with the air gauge in the lower left position. I also found a gauge panel with a 5000 rpm tach with the fuel gauge under it and a 100 mph speedo. I am going to have an overhead console and can put the radio up there so deleting it from the dash is not a problem. Does anybody have any pics of a dash with gauges put in the right side vent position? I did find a pic of what looks like a truck dash with those 2 extra holes added. I have seen a few where they made a plate and mounted them in the plate but I am after the factory look so I hate to do them that way. Any suggestions on how to construct it?
