No. It seems as though GM started the build with the dash, and built the rest of the cab around it. I have done it, but I also replaced the entire cowl at the same time. There has to be over 100 spotwelds to cut out in order to remove the dash. I was not able to get the dash out without cutting the dash in half. Putting in the brand new dash was doable with the entire cowl out of the way, but I will never do a dash replacement ever again!
