replacing dash w/aftermarket gauges

My dash is hacked up so I'm going to replace it with another dash which I have made a large benzel type aluminum face plate for. I have the w/shield out and want to start to pull the dash but figured I would ask here first what I'm getting into . In my mind pop out dash ..wire gauges to alt /fuel/oil pressure/batt./water.temp/ tach/speedo done. Leaving sterring column alone. Now thats my bazzaro mind what is reality . Need help thanks ..1970 swinger
