anyone done or have info/pics with the 19+ bed on the 7-13 style silverado. It looks way better than 14-18 body lines so im thinking about doing it.

Hey guys, new here and got a question. I cant for the life of me to get the blend door to stay in alignment on my 08 silverado. It appears that once I get it aligned and then turn the key off then back on that ot goes back out of alignment. Is there a trick to this? I usually set the knob and flapper to vent. Once i get it put together and turn key off, all the hard work quickly becomes useless.
