Hey guys I am new to this site but I thought that I would post something on my conversion. I read in a magazine about the conversion and decided to do it on my 99 GMC 1500. I went and got a dash out of a wrecked 05 chevy pickup along with an ash tray(I wanted to be able to return everything back to original if things didn't work out). I failed to grab the 05 stereo basket therefore I had to make things work with the original. I move the thermostat controls down by drilling new holes for the clips about 1/2 inch below stock. That solved that problem. A double din does not fit into the slot of the original stereo therefore i had to make additional cuts in the old stereo basket to accommodate the larger double din deck. I spent a lot of time on these cuts to ensure near perfection. Eventually i was able to slide the new deck directly into place, The deck snug enough to not have to do any kind of mounting. After all of this, I made all of the connections and slid everything into place and put the dash back on. I turned out good in my opinion, the only error that i find is that the new dash cuts off a little bit of the defrost emblem. Just for kicks i replaced all the stock components to ensure my self that everything I did was reversible if i wanted.
